• Question of function of time series

  Hi all
  
  I use the function of time series for year there are recipes, in fact table, the date is 2007 to 2010, but related,.
  
  It has a row of 2011, 2011 income is null and income year is 2010, report as follows:
  -----
  income for the year year_ago_Revenue
  2007 __50___
  2008 __80___ 50
  __100___80 2009
  2010 __120___100
  ___120 2011
  
  I want to delete the line of the year 2011, how can I do this?

  Since you only ask how to get rid of the line of 2011, here are two ways:

  (1) filter on column Time.Year <> 2011

  or better

  (2) filter on column Time.Year <> YEAR (CURRENT_DATE) + 1

• How to use properly the function of time series dynamic H-T-D

  Hi all.
  
  Our time Dimension goes as default
  Period
  -Total year
  -Qtr1
  -Jan
  etc...
  
  Now when I put in place HTD (absence of any explanation on the Documentation)
  I put the generation at level 2. Nice function that much is done that for a YEAR, summarizes the total for the year given the current month. What we try to accomplish is to get the values of all data saved on the datal summary current current. Now, this can happen years being in a dimension of differnet. So my main question. Is this possible to do? and what is the main function of H-T-J? Thank you.

  So that HTD make sense, your time Sun will have to be an exercise in cross on the model where your campaigns and periods are in the same Sun

  Time
  -2009
  -Q1
  -Jan
  February-
  -2008
  -Q1
  -Jan
  February-
  -2007
  -Q1
  -Jan
  February-

  In this example CDA would set at Gen2 and HTD would be set at Gen1.

  If your year and periods are of different dimensions so cannot use DTS to run story in the numbers of the date. Derwiche woul in place you put calculated members using formulas of Member and the @XRANGE function.
  (you might be able to do it without @XRANGE, but it would be useful)

• Best approach to model Time series Calc

  Hello comrades,.

  Please let us know the best way to use the calculation of time series in the reports (IE last YEAR, BAT etc.).

  Since many developers odious at this stage

  to share your ideas and suggestions how to model side RPD and reports, while it would be easy to avoid any mistakes or false calculations.

  Thanks in advance...

  Hello

  The easiest is to simply use the provided time series functions out of the box: to use it all you need to do is set up correctly your time dimensions (levels and keys) and the function will do the job.

  Another option may be to model the time series you need as physical join and amounts by a natural aggregations of the rows returned. For this one, you have 2 options: create the values on the side on the side of time dimension or fact. Depending on how you will you need to add additional columns in your MDB to represent the values of time series.

  It really depend on several things to decide which option to use. Start with the output of the function box and there are many chances it will be just enough for most needs.

• Calculation of the variation without time series?

  Hi all.
  
  I have a pivot table like the one below. Time series is not implemented in the RPD, for performance reasons. Is it possible to calculate the difference between two measurements on two different dates in a pivot table (column difference below), similar to what we achieve by using the function of timeseries AGO(). The dates are chosen by the user from a dashboard prompt, so I don't know if the calculated item apply here and the dynamic elements ($1, $2) does not work too. The PivotTable contains more columns and rows as the example below.
  
  ___Dates
  Product___01/10/11___02/10/11___Difference
  A__________10_________15___________5
  B___________8__________6___________-2
  C___________8__________8___________0
  
  Thank you.
  
  Kind regards

  Hello
  With the help of $2 - $1 in the news of the elements calculated under pivot table view.
  Ex:

  10/01/2011 diff name 10/03/2011

  423 400 23 dev

  Let's date = 10/01/2011 see as $1

  to date = 10/03/2011 referd $2

  * $2-$1 will get a difference of two date... fully automatic *.

  * 100% it will work... I have also implemented the same *.

  Thank you

• Time series: finding max and min for each month

  Hello world. I'm working on a datasheet that has collected the data points for all day for the past 15 years.

  A column stores the date and column B contains a numeric value.

  I want to do the following:

  Create a new table (call it table #2) that:

  (1) is now a time series on a monthly basis (column A contains "year month"). This is why the table contains a header and 15 * 12 = 60 rows of data

  (2) B Col contains the Max value of this month.

  (3) C Col contains the value this month min

  Table #2 should be calculated automatically because I need to find these values for several series. Any ideas?

  Here is a way that I came up with

  

  In the table above, your original data is in columns B and C.

  I've added three additional columns (A, D and E):

  D2 = Year (B2) & NUMTOBASE (MONTH (B2), 10, 2)

  It's shorthand dethrone select D2, and type (or copy and paste it here) the formula:

  = Year (B2) & NUMTOBASE (MONTH (B2), 10, 2)

  E2 = IF (D1≠D2, 0, E1 + 1).

  Select copy of D2 to E2,

  Select cells D2 at the end of column E, block

  A2 = D2 & NUMTOBASE (E2, 10, 2)

  Select A2, copy

  Select A2 at the end of the A2 column, paste

  now create a second table summary as shown:

  

  For 'Summary Table 2016:

  the first four lines are the lines of header

  There are 35 total lines

  Enter the year in cell B1

  A5 = −4 LINE)

  B5 = SIERREUR (VLOOKUP ($B$ 1 & NUMTOBASE(B$4,10,2) & NUMTOBASE($A5,10,2), data: $A:$ C, 3, 0), "")

  Select cell B5, copy

  Select cells B5 at the end of row 5, dough

  Select A5 thru M5, copy

  Select cell A5 at the end of the M column, paste

  B2 = MIN (B)

  B3 = MAX (B)

  Select the cells B2 to B2, copy

  Select the cells B2 through M3, dough

  now duplicate the table and change the year to 2015 for the next year.

  You can duplicate this table as necessary to summarize a year

• Dynamic members time series (In a BSO Application) can be used in other formulas of Member, rules of business or Calc Scripts?

  I am building an application of OSI to refer to values for a YEAR in several calculations. Before you enable the DTS, I wanted to make sure that they can be referenced in the formulas (used in IF conditions to check the values against a value of Member A-T-D)

  Dynamics of time series can be used only to display values DTS EN reports or in smart view retrieves. You cannot use them in the form of Member or Calc. I think the best way would be to add a version with a formula that adds every month until this month for CDA or a different scenario.

• Time series by using Oracle Data Mining? Is there any equivalent of ARIMA in the MDGS?

  Hello

  I followed the extraction of data from Oracle Press book. I applied regression models to predict continuous variables.

  My use case is to predict the market price of stocks based on historical data.

  I see there R packages to do. Some popular methods that are widely used are ARIMA (Autoregressive integrated mobile average).

  Is there such an offer out-of-the-box in the MDGS?

  Pointers / whitepapers, or do we use component regression?

  Thank you

  Chrystelle

  Hey Lulu,

  MDG does not have an implementation of time series which is precisely part of the SQL in the algorithms of db.

  But AAO (Oracle Advanced Analtyics, ODM is a part of) has an implementation of time-series Oracle which may be useful for you:

  See ore.esm model, documented with examples here: https://docs.oracle.com/cd/E57012_01/doc.141/e56973/procs.htm#BEIEGCDG

  We also have the preparation of data for time series capabilities, listed here: https://docs.oracle.com/cd/E57012_01/doc.141/e56973/procs.htm#BEIJHHCG

  May also be interested to Marcos Campos blog on time series using the current characteristics of ODM/DB: Oracle Data Mining and Analytics: time series Revisited

  Hope it will be useful.

  THX, mark

• SmartView and dynamic time series

  All,
  
  I just heard this:
  
  Dynamic time series is used in other applications on the reports and work as expected in the financial information. However, it does not correctly work with SmartView.
  
  
  Is this true? You cannot get DTS reports in SmartView? Version 11.1.2.1

  Have a read of http://docs.oracle.com/cd/E17236_01/epm.1112/sv_user/sel_dts.htm
  or are you saying EN reports in Smart View does not work

  See you soon

• Dynamic time series in a form

  It seems to allow me to add it. Click on the Member, A-T-J of medium-sized options. He then Let's save me it.
  
  But then not let me open the form (errors).
  
  Anyone know if this is a bug or if there is something missing.
  DTS works in reports
  I use version 11.1.2.1

  It may depend on the form design
  for example 10226960 - cannot open a data form that includes members of the time series dynamics (DTS) and has the option to remove the missing blocks selected.

  See you soon

• Time series graphics display data inappropriate for a continuous analysis

  Hi all
  I've marked in months as chronological key in my MDB layer, but I still cannot display data correctly in my chart of time series, because it shows data for analyses continuously when you create the chart. Can someone help me with the same.
  
  
  Thank you

  What type of data is your key? The chronological key is required for time series formulas (there etc.).

  The time series graph requires a date or datetime data type work - maybe a new column with the first of the month / help? Kind regards

• Time series Question - how avg for children period but no parent

  I have a calculated account, trying to get the average to the level of the child of the period, but have the Parent period level make a right calc on the totals. My cube is configured like this:
  
  
  Period
  -Jan
  -JanWeek1
  -JanWeek2
  -JanWeek3
  -JanWeek4
  -JanWeek5
  Account
  -Hours billed
  -Revenue
  -Avg Houly rate = 'Recipes' / 'Billed hours' (I have time series data, the average value)
  
  My problem is that during the week level things are on average correctly, but at the level of the month, that is by taking the average of 5 weeks. How can I get if it just look at the total revenue for the month divided by the total number of hours billed (by having the weeks do everything an average?)
  
  Thanks in advance for any guidance.

  You probably don't need to use all balance of average time for this calculation. I suggest defining members in time balance zero, then label it as 'Dynamic Calc' and label it as "Two-Pass", ensure that the income / hours calculation after the period roll-up.

  I think that you would give the desired result.

• Time series OBIEE 11 g: regression on there / function to this day?

  Hello
  
  We test the migration to OBIEE 11 G.
  We are currently in version 10.3
  
  We have a problem on AGO / OBIEE TO_DATE functions that returns null results on existing reports.
  In version 10.3, these functions operate properly with the real TIME dimension.
  
  Here's how we designed the time Dimension:
  
  TOTAL-> year-> shift-> MONTH->-> DATE_KEY, FULL_DATE WEEK
  
  DATE_KEY is a number and referenced on our fact table as a foreign key.
  
  CREATE TABLE TD_DATE
  +(+
  DATE_KEY NUMBER (11) NOT NULL,
  DATE OF FULL_DATE
  THE WEEK NUMBER (2),
  NUMBER OF THE MONTH (2),
  NUMBER OF QUARTER (1)
  NUMBER OF THE YEAR (4).
  TOTAL_DATE VARCHAR2 (11 BYTES)
  +)+
  
  Database version: Oracle 11 g
  
  All items in the dimension are chronological touch (except full date) to optimize performance.
  
  Have you encountered similar problems in inplementation of AGO / TO_DATE function on the 11 g version?
  
  Thank you

  A month have always the same number of weeks and begin with the first day of a week?
  If it is not the case, your dimension is not good when you're doing a report on the grain of the week for a year, for example.

  Here's a checklist:

• implementation of a function of time transfer real Labview program

  Hello

  I want to spend my control signal U through the 146 function /(S+276) for U_filtered

  How do I?

  I tried a low-pass filter, but I have the same results in comparison with Matlab.

  I mean I want to have:

  U_filtered = 146 /(S+276) * U.

  I have attached a picture for the signal U (yellow) and U_filtered (pink) in Matlab.

  I want to use in a real-time application

  Thank you

  How you implement the function of transfer in labview?

  I think this should be a separate implementation and maybe you already do. So forgive me if this is something you already know.

  Please see http://en.wikipedia.org/wiki/Low-pass_filter#Discrete-time_realization for an excellent time discreet introduction, low-pass filters.

  Essentially, you have to implement a discrete equation to achieve this. Something like:

  y(k+1) = 0.53 * alpha * x (k) + (1-alpha) * y (k)

  where alpha is related to the low-pass frequency and the frequency of sampling by alpha = flp /(fs+flp), flp is the low frequency of success and fs is the sampling frequency.

  In your case, flp = 276 and fs, it's whatever you choose to implement: it is the speed at which your loop runs on the RT or the FPGA or whatever. If speed is not a problem, I recommend 5000 rad/s or above as a starting point.

  The factor of 0.53 above is just the gain of the filter described you 146/276.

• How to find the mobile average for perticular time step for the same time series

  Hi all

  I'm new in labview and I have a question. I have a huge text with the value of different pressure of various ports.

  I do the VI in which all first I read the text file and identify the column of perticular port. In this column, there is pressure value 32768.

  Port of Port 102 times Num Port 101 103... Port 532

  0         1

  2 0.001

  .          .

  .          .

  50 32768

  And reading this all takes 50 sec and I divide this reading in 4.5 sec... There are in all 4.5 sec 2969 values...

  Now, please check the attached VI... I am able to find the average value in step 12 2969 value time...

  Now, I want to do is to find the average value of 2969 (2970 to 5938) values with time of 12 steps and so on up to 32768. It is 11 times in the series...

  So anyone can change my VI?

  Thank you

  Hello

  Thank you very much. It's the perfect VI that suits my needs.

  Thank you again... Have a great day ahead.
