A regression residual is the difference between the actual value of a dependent variable and the value predicted by a regression model. The formula for calculating the residual is:
Residual = Observed Value - Predicted Value
Enter or paste values for the independent and dependent variable in the spreadsheet below and then click on the 'Calculate' button to calculate the residuals for each row.
The linear regression equation is :
ŷ = + ()*x
The predicted value and residuals are shown in the table below:
