How to Find Regression Equation | Simple / Linear ...
The regression equation then simplifies to: (3) ZY(= ß1Z1 + ß2Z2 + ß3Z3. The value of the multiple correlation R and the test for statistical significance of R are the same for standardized and raw score formulations. Test of R Squared Added

To create an array formula you select the cells in which you want the results (ie the slope and intercept) to appear, enter the formula and press control-shift-enter and Excel will enclose the formula in curly braces to signify that the result is an array of values. The syntax to calculate each of the terms in the regression is as follows:

You will see when we do a later exercise, that the result from the hand built formula is more than tolerably close to Excel’s result. Simple Linear Regression. If the correlation coefficient indicates a sufficiently strong relation ship (direct or inverse) between variables, you may wish to explore that relationship using regression techniques.

Since in regression our goal is to minimize the unexplained variance and have most of the variance in explained by the regression equation, then to have a significant result, we would expect the -test statistic to be greater than 1. Note that an alternative formula for the -test statistic is . Can you show this is true??
