Examining Residuals in Simple Linear Regression
... • make residual plots (residuals vs. fitted values, i.e., êi vs. Ŷi ) to see if the standard deviation of the residuals remains relatively constant as the fitted values change. Residual plots also help us verify whether a linear relationship between the mean of Y and X seems appropriate. Residual ...
