How to activate a chart like LINEST

In Excel for MAC, I select the area of the table. In the open left corner, I write the LINEST. After this, hay, press shift + command + entry and displays the result in the cell. How can I do the same in NUMBER?

I suggest reviewing built-in browser information.  When you type the sing equal in a cel, in mode 'formula' and browser features appear on the right:

Enter the function in question in the search field.

The short of it is...

= INDEX (LINEST (a2: A6, B2: B6, 1, 0), 2) returns about 0.0342960288808646, which is b.

Therefore, integrate the function of lines in a call to index() in order to access the elements of the array.

I'm sticking with linest here:

The LINEST function returns a table of statistics for a straight line that best fits the data using the method of least squares.

  • LINEST (known y - values, values-x-known, different from zero-ordinate at the origin of other stats)
    • known y values: a collection that contains the values of are known. known y values must contain numeric values. If there is only a collection of known x-values, the known y values can be any size. If there is more than a collection of known x-values, known y values can be either a column containing the values or a line containing the values, but not both.
    • values-x-known: an optional collection containing the known x-values. known x-values must contain values of number. If omitted, it will be supposed to be a game of the same size as known y - valuesbeginning with 1 - for example, 1, 2, 3 if there are three values are known. If there is only one set of known x-values, values known-x, if specified, should be the same size as the values are known. If there is more than one set of known x-values, each row/column of known x-values is considered to be a game and the size of each row/column must be the same as the size of the row/column of values known there.
    • different from zero-y-intercept: a modal value specifying how the intercept (constant (b) must be calculated.
      • normal (1, TRUE or is omitted): the value of the intercept (constant (b) should be calculated normally.
      • force the value 0 (0, FALSE): the value of the intercept (constant (b) should be forced to 0.
    • more stats: an optional modal value specifying if the additional statistical information should be returned.
      • no stats additional (0, FALSE or omitted): do not return the additional regression statistics in the table returned.
      • additional statistics (1, TRUE): Returns the additional regression statistics in the returned array.

Notes

  • The values returned by the function are contained in a table. A method for reading values in the table is to use the INDEX function. You can wrap the LINEST function within the function INDEX: = INDEX (LINEST (known y - values, values-x-known, ordered originally, other stats), y, x) where y and x are the index line and column of the desired value. If the additional regression statistics are not returned (more-stats is FALSE), the returned array is a deep line. The number of columns is equal the number of sets of known x-values + 1. It contains tracks from the line (a value for each row/column of x-values) in reverse order (the first value refers to the last row/column of x-values), then the value of b, the y-intercept. If the additional regression statistics are returned (more-stats is TRUE), the table contains five lines. See more information on this table immediately following the examples.
Examples
Given the following picture of known-x-values(cells A2:A6) and known y values (cells B2: B6):
A B
1 X THERE
2 0 -1
3 8 10
4 9 12
5 4 5
6 1 3
= INDEX (LINEST (a2: A6, B2: B6, 1, 0), 1) returns approximately 0.752707581227437 for a normal given (1) non-zero-ordinate at the origin. This is the slope of the best-fit line because we said that we wanted the first value of the array returned by INDEX and we have specified that one set of known x-values. = INDEX (LINEST (a2: A6, B2: B6, 1, 0), 2) returns about 0.0342960288808646, which is b, the point of intersection of the best-fit line. The intercept was originally returned because we said that we wanted the second value in the array returned by INDEX, which would be the second value because we have only specified a set of known x-values.

Content of the additional statisticsLINEST table may include additional statistical information in the table returned by the function. For the purposes of the following discussion, assume that there are five sets of x values known, in addition to the values of y known. Suppose further that the known x-values are in five rows in the table or five columns of the table. On this basis, the array returned by LINEST contains the following values.

1 2 3 4 5 6
1 S5 S4 S3 S2 S1 b
2 SE5 SE4 SE3 SE2 SE1 SEb
3 C SE's
4 F DF
5 R1 R2

Row 1, column 1 contains S5 (the slope for the fifth set of known x-values) continuing until the 5 column, containing S1(the slope for the first set of known x-values). Note that the slope related to each set of known x-values are returned in reverse order. The last cell in row 1 contains b, the y for x values known. In our example, this would be row 1 column 6. row 2, column 1 contains SE5 (the standard error for the associated coefficient to the fifth set of known x-values) continuing until the 5 column, containing SE1(coefficient of standard deviation for the first set of known x-values). These values are returned in reverse order; in other words, if there are five sets of known value x, value for the fifth set is first returned in the array. It is the same way the slope values are returned. The last cell in row 2 contains SEb, the standard deviation associated with the value of the y-intercept (b). In our example, it would be the line 2, column 6. row 3, column 1 contains C, the coefficient of determination. This statistic compares the values are estimated and actual. If it is 1, there is no difference between the value is estimated and real value there. This is known as perfect correlation. If the coefficient of determination is 0, there is no correlation, and the particular regression equation is not useful to predict a value y. line 3, column 2 contains SE's, the standard deviation associated with estimating the value y. line 4, column 1 contains F, F observed value. The observed F value can be used to help determine if the observed relationship between the dependent and independent variables occurs by chance. Line 4, column 2 contains degrees of freedom, DF. Use the statistics of degrees of freedom to help determine a confidence level. Line 5, column 1 contains1, the sum of squares regression R. Line 5, column 2 contains R2, the residual sum of squares. Here are some things to keep in mind about the additional regression statistics table:

  • It does not matter if the known x-values and known values are in rows or columns. In both cases, the returned array is ordered by lines, as shown in the table.
  • The example assumes that five sets of known x-values. If there is more or less than 5 years, the number of columns in the table returned change accordingly (it is always equal the number of sets of known values x + 1), but the number of lines would remain constant.
  • If the additional regression statistics are not specified in the arguments to LINEST, the returned array is equal to the first line only.

    You want to switch between the internal and dedicated GPU. Right?
    You said that you have an ATI graphics card.
    For laptops that are equipped with the graphic chipset ATI something like that is not possible because not supported

    As far as I know, you can do so with the nVidia GPU support the Optimus technology.

  • Qosmio F50-126: how to activate the integrated graphics card?

    Running Windows 7 on F50 - 126.
    After checking my specs on the site Web of toshiba, here are the details on my graphics card: -.

    Manufacturer: NVIDIA;
    type: NVIDIA; GeForce; 9700 M GTS supporting TurboCache; technology
    memory: 512 MB dedicated VRAM (up to 1 791 MB of total available graphics memory using the TurboCache™ technology with 3 GB of system memory)
    memory type: GDDR3 (800 MHz) video RAM (resp. RAM video and system memory combined)
    connected bus: PCI Express 16 x

    I want to know if I can turn on my integrated graphics card. I know that clicking on powersave suppose to turn off my 9700 m and go to the integrated card, but the laptop did not want it actually disabled.
    Like, watching a video or a game of battery the difference between "Powersafe" and "Balance" is not that much.

    The computer seems to work at full power.
    Because I remember when I had Vista installed, the game and used trolling videoes. But on windows 7 it doesn't. Anyone know how to activate the integrated card?

    I have my computer updated completely and everthing... How d I do not know if my card is turned on or off?

    Hi mate

    I'm a bit confused of m.
    Why?
    Because you ask about activation and deactivation of the graphics card (integrated).

    First of all, there is ONLY a single graphic chip!
    It s a GeForce 9700 M GTS graphics card.

    The graphics chip supports the 512 MB GDDR3 own (he dedicated video memory s) and it s is always available!

    In addition, the chip supports shared system memory. It depends on the available main memory!

    For example:
    * With the help of Win 32 bit system *.

    System memory: * 2 GB *.
    Dedicated video memory: 512 MB
    Shared system memory: 767 MB (using 3 GB of RAM you 1279 MB)
    TOTAL available graphics memory: 1279 MB (1791 using 3 GB of RAM)

    System memory: * 4 GB *.
    Dedicated video memory: 512 MB
    Shared system memory: 1279MB
    TOTAL available graphics memory: 1791 MB

    * With the help of Win 64 bit system *.

    System memory: * 2 GB *.
    Dedicated video memory: 512 MB
    Shared system memory: 767 MB
    TOTAL available graphics memory: 1279MB

    System memory: * 4 GB *.
    Dedicated video memory: 512 MB
    Shared system memory: 1791
    TOTAL available graphics memory: 2303

    As you can see the use of Win 64-bit and 4 GB of RAM would be better for the graphics card as the use of the file Win 32 bit with 4 GB of RAM

    However, the requirements for the media upgrade is that you have an operating system already eligible such as Windows XP or Vista installed to use it. Since the Windows 7 end user license agreement.

    15 UPDATES. To use upgrade software, you must first be licensed for the software that is eligible for the upgrade. After the upgrade, this agreement takes the place of the agreement for the software that you upgraded. After upgrade, you can no longer use the software that you upgraded.

    So, if you are always denied, you will just have to reinstall Windows XP or Vista and let it do the verification of eligibility.

    Change the dashboard-> properties of the column (column in which is placed a command prompt). I see "Freeze column" option that can be checked and unchecked.

    But when I go to create a new dashboard and add a column and a dashboard quickly inside.  I do not see "Freeze column" option.

    Is there a way to activate these options as in the configuration of the instance?

    Thank you

    "Frost column" option is possible only in some bases of columns on your page layout.

    How your dashboard page looks like (how are the columns placed in it)?

    If you add 2 columns a side of each other, that you can freeze one on the left, if you put 2 columns one above the other, you can freeze one on the albums etc.
