• Percentile calculation BI

  Hi friends,

  I was bit confused with the calculation of percentiles and explain my scenario. I have the sub report

  In the above I'm not sure how to do the base salary average annual is calculated. I can see the formula substituted for this column as below

  AVG ("salary facts". "' Total annual Base salary" by NTILE ("salary facts". (("" Total annual Base salary ", 2))

  For the two highest rank of the average base salary is below the value with the formula above

  144908.05

  588320.46

  But I'm not sure how it calculates the respective value. Please specify this friends of calculation.

  Thanks in advance.

  Kind regards

  No, the average for this NTILE... it is not based on MAX or MIN...

  NTILE = 5 takes about 20% of the values, once sorted, within each group (TILE).  Here the AVG() function tries to find the average 20% of the values.  So altogether if you had 10 original lines, 2 rows would be in each TILE... at that time, you would average between two values.  If you had 100 lines, then you would seek to average in each groups 5 through 20 lines per group.

• Get the 90th Percentile

  Hello

  I try to extract the max, min and the 90th percentile of the results table.

  I want to the 90th percentile for duration based on the timestamp_ in the order of the CSA.

• Possible new feature percentile?

  Hello
  
  I am running "Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production".
  
  I need to calculate percentiles, so I think I have two choices: PERCENTILE_CONT() or PERCENTILE_DISC().
  I also need to get the same results as SPSS and SAS tools.
  By comparing the results, or versions of Oracle gives the same result as SPSS/SAS. I think it's because of the way Oracle determines which line numbers to use.
  
  Oracle ranks RN = (1 + (classified *(N-1) p), where P is the percentile and N is the number of lines.
  For PERCENTILE_CONT (0.1) of a set of 16 lines that would give a row 2.5 as starting point.
  http://docs.Oracle.com/CD/B28359_01/server.111/b28286/functions115.htm
  
  SPSS and SAS uses the formula RN = P *(N+1) which gives the rank 1.7 for a set of 16 lines.
  
  Now, it would be possible for me to write a PERCENTILE_SPSS() function?
  
  Examples of analytical/pipelined functions I have seen (and written) are happy to use the lines in the game one by one, to calculate a few special min/max/avg/etc.
  For this function, I would need to be
  1. to know the number of lines in the game, since the first call of my function and calculate the percentile as my function "passes" the desired lines
  or
  2 - save all values in the game and calculate the percentile at the end
  
  The first sounds impossible, the second seems expensive for a large table.
  Any suggestions?
  
  
  Kind regards
  
  Tomas

  the second seems expensive for a large table

  Yes, you are probably right. Write your own aggregate function involves many context switches between SQL and PL/SQL Engine runtime and possibly abuse of PGA memory keeping excessive values in tables and therefore is unlikely to perform as well a solution pure SQL, however desirable encapsulating function may at first seem.

  I think using COUNT (*), to get the number of lines and follows the specification for PERCENTILE_CONT http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions110.htm#i1000909 will give you what you need to calculate, for example)

    2            MAX (CEIL (prn)),
    3            MAX (FLOOR (prn)), MAX (nr),
    4           (MAX (CEIL (prn)) - MAX (prn)) *
    5              MAX (DECODE (rn, FLOOR (prn), nr)) +
    6           (MAX (prn) - MAX (FLOOR (prn))) *
    7              MAX (DECODE (rn, CEIL (prn), nr))) percentile
    8  FROM   (SELECT ROWNUM rn, COLUMN_VALUE nr,

   13  WHERE  rn IN (CEIL (prn), FLOOR (prn));

  Edit: with hindsight you may prefer the ROWNUM ROW_NUMBER analytic function because it would allow you to order explicitly by nr with unsorted data.

• How to calculate the 99th percentile of a stream of number...

  Environment:
  
  Oracle 11.2.0.3 EE on Solaris 10.5
  
  I have a stream of numbers (for example 1000), I need to calculate the 99th percentile of the distribution of this stream in such a way that when a new ' number is introduced, I can tell if the new number is above the 99th percentile of the distribution of my workflow.
  
  I don't have a good idea of the nature of the distribution if it's important.
  
  I am NOT, I repeat NOT a statistician! :-)
  
  I read the docs on the different functions available, ntile, percent_rank, percentile_cont, percentile_disc, etc. I also read a lot of articles referenced via Google.
  
  The examples are not exactly what I'm trying and I was unable to get the result I need by trial and error (mostly!).
  
  All suggestions are welcome!
  
  If you need additional information, I will try to provide what I know.

  Hi, Gary.

  Hi Frank

  Well to try to facilitate the description of periods, I managed to confuse the issue a little more.

  Sorry about that.

  I need to use days not months. The script will be executed every day and watch period of ago 210 days to 31 days following there from 30 days at present.

  With respect to the expected result, I need somehow calculate what turnover represents the 99th percentile (or 90th everything that works in the example) and store that in my table of this customer.

  Then after a CREATE TABLE statement for this table and you want that it contains, given the data published in the sales table, after it is filled.

  Another process on the whole will consider the last average of 30 days and determine if this average exceeds sales 99th percentile figure and initiate an action (alert email, etc.) if it is.

  My problem is that I don't know how to calculate this 99th percentile number.

  After the sample data, I'm guessing it should be close to the number of SD 3, but after reading your comments, maybe that's not correct.

  That's my guess. Sometimes deviations corresponding to percentiles, sometimes they did not. People choose one or the other, depending on what amounts to their data, and what they want to show on these data. Your client has apparently chosen percentile. Unfortunately, we do not seem to know something about the problem.
  Before you can solve this problem for your customer, you must understand what the problem is. Talk to your client and know exactly what is wanted here.

  Here is one possible approach.

  WITH     got_month_avg     AS
  (
       SELECT       custno
       ,       AVG (amount)     AS month_avg
       FROM       sales
       WHERE       tran_dt     >  SYSDATE - 30
       AND       tran_dt     <= SYSDATE
       GROUP BY  custno
  )
  ,     got_threshold_amount     AS
  (
       SELECT DISTINCT
            custno
       ,     PERCENTILE_CONT (.4)          -- or .99
                WITHIN GROUP (ORDER BY  amount)
                          OVER ( PARTITION BY  custno )          AS threshold_amount
       FROM    sales
       WHERE     tran_dt     >  SYSDATE - 210
       AND     tran_dt <= SYSDATE -  30
  )
  SELECT       a.custno
  ,       a.month_avg
  ,       t.threshold_amount
  FROM       got_month_avg          a
  JOIN       got_threshold_amount  t  ON  t.custno  = a.custno
  --WHERE       a.month_avg     >= threshold_amount
  ORDER BY  custno
  ;
  

  Output:

  `   CUSTNO  MONTH_AVG THRESHOLD_AMOUNT
  ---------- ---------- ----------------
           5      126.5           4812.6
          26 4602.44444           3102.2
  

  I set the WHERE clause comment, just so that we could see the results of each custno. I also put the extremely low threshold (40th percentile) just for a custono would be selected if you are not using the WHERE clause.

  Subqueries are average in the last 30 days and the 40th percentile for 180 days before that. Let's take a look at custno = 5. There were two rows in the last 30 days (225 and 28 amounts), then the average in the last month is (225 + 28) / 2 = 253 / 2 = 126,5.
  Within 180 days prior to that, he had 7 amounts, in ascending order:
  1st (0th percentile): 647
  2nd (17th percentile): 1869
  3rd (33rd percentile): 3065
  4th (50th percentile): 7434
  5th (67th percentile): 8435
  6th (83rd percentile): 9393
  7th (100th percentile): 9712
  Since (for now), we are interested in the 40th percentile. It will be more than number 3065 (33rd percentile) and less than 7434 (50th percentile), 3065 to 7434, somewhat 40% being somewhat closer than 33% to 50%. This number turns out to be 4812.6.

• shares advanced; expressions; percentile of the right answer

  Hi all! It seems that I got my custom with two questions and all peachy keen video question slide BUT the percentile (TFScore; textbox I inserted and controlld with advanced actions) will return not populated. It is just empty return when I click 'submit '.

  This leads me to believe that this is something that has to do with the expression that I'll put up...

  Can someone give me directions (more). Maybe I'm forgetting somethings or place the expression in the wrong place...

  The percentile is a standard object, and it is not allowed to add it to a conditional line of commands. As a result, their not all connected to each other through ' placing them in the same command line. I hope I'm being clear.

  How this action Standard (%) is related to the events in the file conditional line, you initially create? the last part, that I got was the part 'show '.

  When I get to the part 'show' conditional events and be prepared to add a 'standard' it opens a new set of commands to be applied. How is it that these actions are related to the same line of Board actions, I created? What I am doing wrong?

  I also tried, while remaining in the part 'show' of the line of conditional events. by clicking in the 'IF' part and which actually hide or overlap so that you get a hidden part or a continuation of the line of action, but I don't think that I'm just doing.

  Thanks in advance.

  Hi Joseph,.

  As I have already answered in other messages: your question can be understood (and I'm someone who know a bit about advanced actions) as a result of your use of terminology and a rather confusing way of writing on this issue. Here some examples:

  • first paragraph: TFScore, assume that it is a variable that you included in a container of text (legend or form)?
  • second/third paragraph: "expression": what do you mean? Expression is a statement/command that can be used in a tip action, you're talking about that?
  • third paragraph: "wrong place" are you talking about this command sequence in a tip action?
  • 4th paragraph: "percentile" = standard object, that is? Stock items are listed in the Insert, Standard objects option, you talk about what? I think that it is a variable, but is not a standard object, and it is just my intuition which is now staggering when I read your questions. Each standard object can be added to drop-down lists in advanced actions, provided that the command can be applied to this object (like hide, show...)
  • 5th paragraph: "action Standard related to the conditional line of the event" even my intuition of Captivate is to abandon?
  • 6 paragraph 'see the part of the line of conditional events' I get crazy, big headache and stops...

  Just for the record: as a teacher of long date, I especially to guess a question after the first few words student pronounced, even when presenting at international conferences. But with you I feel like a stupid fool, stupid. Maybe the stem will understand what you want, my lack of English is perhaps the cause?

  Thank you

  You must understand how this is difficult to do and then trying to figure out if there is a way to do it virtually. To start, we need to understand and recognize that the way Excel calculates PERCENTILE is not the way percentile is usually calculated. The first thing you have to determine is if you want a percentile statistics, or if you want to that Excel PERCENTILE. I suggest you read up on it in Wikipedia to get some perspective on the differences. Given that the Percentile can be calculated in many different ways, you can start with the MDX function built in Essbase Percentile() - found in the tech ref

  An example would be

  Percentile ({[location] .children}, [price], [classification])

  Where your game is the children of location and rely on it the price and calculation percentile based on the value in a row in the occurrence.7 (in reality must be 70, see next paragraph). You'll find maybe easier to code simply difficult this value in the function if it does not change

  Percentile ({[location] .children}, [price], 30) Note that I used 30 and pas.7. Essbase requires a value between 0 and 100 and looks like he does in ascending order, so 30 is equivalent.7. Given your data values, using this function, you must come with 32.2.

  Now, to get like Excel to do, I tried to put everything in a neat member formula but I had stopped operating problems that have been driving me crazy where Essbase was essentially to ignore certain parts of the form. I don't know if this was due to a bug or just the way it works. The way in which I supported in the calc Excel being procedural, I decided to break it just straight up in an MDX query. If you wanted to do in a plan, you could make the members for all of my 'WITH MEMBER' clauses and how translate, he notices that he's going to be difficult to understand. I've also simplified it to two dimensions with just measures and location. Under location, I had 12 members to capture the 12 values and then I ran the following query, see all downstairs for the results and note that in this case, I went back to the use of that the 0.7 you had in your Excel examples to try to keep apples to apples.

  WITH
  MEMBER [Measures]. [Calc1] AS
  ' Order ([location] .children, [Measures].) [Price]) .item)
  (IIF)
  Rest ((([Rank]) * COUNT([Location].children)))<>
  Int ((([Rank]) * COUNT([Location].children))) + 1,.
  Int ((([Rank]) * COUNT([Location].children)))
  )) - 1)'

  MEMBER [Measures]. [Calc2] AS
  ' Order ([location] .children, [Measures].) [Price]) .item)
  (IIF)
  Rest ((([Rank]) * COUNT([Location].children)))<>
  Int ((([Rank]) * COUNT([Location].children))) + 1,.
  Int ((([Rank]) * COUNT([Location].children)))
  )) - 2)'

  MEMBER [Measures]. [Calc3] AS
  "[Measures]. [Calc1] - [Measures]. [Calc2] »

  MEMBER [Measures]. [Calc4] AS
  "[Measures]. [Calc2] + ([Measures]. [Calc1] - [Measures]. [Calc2]) * ([Measures]. [Classification]) »

  SELECT
  {[Measures]. [Price], [Measures]. [Ranking], [Measures]. [Calc1], [Measures]. [Calc2], [Measures]. [Calc3], [Measures]. [Calc4]} ON AXIS (0).
  {[LOC1]} ON AXIS (1)
  OF Test3.Test3

  Axis-1 (price) (Rank) (Calc1) (Calc2) (Calc3) (Calc4)
  ------------------------------------------------------+---------
  (LOC1) 7 0.7000000 9 22 31 28.3

  There are a lot of things at play here regarding this operation at higher levels compared to lower levels etc. So to be honest, I think you take a big task here. Essbase and statistics is a poor relationship, he made some ok stuff, but in general there are statistical packages generally better there. It's an interesting thing to watch, but it will take a lot more work to top and do work - more can be done on a forum user :)

  I hope that I gave you to think. If possible, try to use the built-in function and see if that can meet the need.

  Select percentile_cont (0.5) in the Group (order of measure_column), dim_col

  percentile (0.5)... is identical to the MEDIAN function. Maybe you can consider using this one instead.

  such as:

  select median(measure_column)
  from table_name group by dim_col
  

  This won't help with percentile (0.9) of the cause.

• Function percentile &amp; percentage in SQL or PL/SQL?

  Hi all
  I was wondering if there is
  

  Percentile or percentage functions in SQL or PL/SQL  to calculate ??
  
  I came across percentile_rank , but i didnt find really good example online .... so i wasnt sure if thats right function for calculating  percentile 

  Any example will be great!
  
  Thank you very much!!!

  Hello

  You don't need the functions for that; Just use the / division operator:

  SELECT  x.*
  ,     TO_NUMBER (value_amt) /
       NULLIF (TO_NUMBER (cnt), 0)          AS avg_value
  FROM      x
  ;
  

  During the validation of the sample output, it is better just to post the actual production, not a table having the same output.
  For example:

  VAL CN AVG_VALUE
  --- -- ---------
  100 6      16.67
  200 5      40.00
  500 10     50.00
  700 12     58.33
  900 14     64.29
  

  It's actually the output I got from the above query.

  Store numbers in a column of string just asking trouble. Use a column to the NUMBER instead; you will avoid the mistakes, and you won't need TO_NUMBER calls in queries like the one above.
  If you are certain that the NTC is never 0, then you need not NULLIF. "NULLIF (cnt, 0)" to avoid a division by 0 error by returning NULL rather than 0.

  The part number, the other Member has suggested is for a complete motherboard. If your laptop is brand new that will likely violate the warranty. You really want to go this route?

  If you feel that is worth the upgrade of the motherboard and the video, then you would be better to return the laptop. Buy one that has the features you want rather than take the risk of damaging the laptop during disassembly and reassembly.

  Re: 'for the discrete graphics, power supply unit changes may have to do usually. But since it listed as compatible tips in the user manual, which may not be a problem. "This is not correct. Laptop models with maps installed discrete graphics require a 65 Watt power adapter instead of a unit of 45 w.  Be specific in your statements and your suggestions.

• EliteBook 2740 recharge does not and HP product Assistant crashes when you start the battery check

  I just buy an elitebook 2740.  When I hover over the battery and plug icon in the taskbar, it says do not charge battery.  I tried to uninstall the ACPI compatible driver in the Device Manager and scan for new hardware to reinstall it, and it worked the first time.  But now it does nothing.  When I open produced tune, I get an error message and the program crashes when starting the battery check.

  Yes, I downloaded and installed the BIOS and chipset drivers and followed by the shutdown sequence.  It's the job niow.  I called Technical Support and learned that the battery does not load when it reaches a certain percentile because the computer recognizes it has a good charge.  When it is less than 95% fresh or so, it will load.  Mine does not work correctly.  Appreciate your help, I wasn't aware of this design feature before now.  Overall it was a good exercise.

• How can I quickly get its main value of amplitude and frequency of measurement of Spectra

  See attached vi. Very well, the chart, I see that the dominant amplitude is 3 with dominant frequency of 100 Hz. But how to do that 3 and 100 of the value from the waveform data in a variable double?

  I think I have the output waveform for measurement of the Spectra vi table and then do some math on it maybe high percentile or something, but that is awkward! Is there a special feature that can quickly the value of amplitude and dominant frequency?

  O! blind me! Use max array and index. Solved already!
