Calculate residuals from linear regression analysis
About Residuals
A residual is the difference between an observed value and its predicted value from a regression model.
Formula: Residual = Observed (y) - Predicted (y-hat)
Standardized residuals are residuals divided by the standard error, useful for identifying outliers (values beyond +/- 2 are potential outliers).
