# To Compute Residuals

- Input the data into two lists (L
_{1}for the x-values and L_{2}for the y-values, for example), and calculate the linear regression equation, using the procedure above. - Select another list in which to store the residual values (L
_{3}, for example) by using the arrow keys to scroll over and up until the name of the list is highlighted. - Press 2
^{nd}STAT to navigate to the List menu. - Select the RESID option by scrolling down to it and pressing ENTER.
- Press ENTER again to populate your selected list with the residual values.

## Special note about computing residuals

You MUST compute the LinReg for your current set of data before asking the calculator to provide the residuals.
