The last section of the regression summary provides the standard deviation about the regression ( residual standard error), the square of the correlation coefficient ( multiple R-squared), and the result of an F-test on the model’s ability to explain the variation in the y values. about this error term as some software do the calculation of this error term in. The results of these t-tests provide convincing evidence that the slope is not zero, but no evidence that the y-intercept differs significantly from zero. There are two basic ways to perform linear regression in excel using.
Clicking OK generates the information shown in Figure \(\PageIndex \beta_0 \neq 0\) Select the radio button for Output range and click on any empty cell this is where Excel will place the results.
Excel’s summary output uses the x-axis label to identify the slope.
