# Linest excel output

Use Excel's LINEST function. Discussion. LINEST computes statistics for a least-squares straight line through a given set of data. The syntax for LINEST is {= LINEST(y-value cell range, x-value cell range, compute intercept, compute statistics)}. Note the braces surrounding this formula since it is an array formula. When you type this formula ... This guide assumes that you have at least a little familiarity with the concepts of linear multiple regression, and are capable of performing a regression in some software package such as Stata, SPSS or Excel.

Steps to use the Linest function in Excel. LINEST function returns several outputs, so to begin, select a 2 by 5 array as shown. Click , the Insert function icon.; In the Insert Function popup menu, choose the Statistical category and then choose the LINEST function. Click OK.; In the Function Arguments window, click the Known y's field and drag your mouse to highlight the y-values.Excel makes it very easy to do linear regression using the Data Analytis Toolpak. If you don’t have the Toolpak (seen in the Data tab under the Analysis section), you may need to add the tool. Go to the Data tab, right-click and select Customize the Ribbon. Select the Add-ins section and go to Manage Excel Add-ins.

LINEST function reads: LINEST(C2:C11,A2:B11,TRUE,TRUE), where x1,x2=A2:B11 and y=C2:C11. Excel only returns one slope, the slope for x2. The slope for x1 is not returned, nor are the additional statistics. I've searched online help and found the explanation referenced in the subject line of this message. MS's

LINEST works just as in the simple linear regression case, except that instead of using a 5 × 2 region for the output a 5 × k region is required where k = the number of independent variables + 1. Thus for a model with 3 independent variables you need to highlight an empty 5 × 4 region.

The Linest function returns the slope and Y intercept of the straight line that most closely fits the data (values a and b above). Note that the function is entered in a single cell, and must be entered as an array function to display both results: Enter the function as usual; Select the output range (A28:B28 in the example above)
