Scaled residuals

WebOne easy application is graphing the residuals of a model. If you imagine a model as a best-fit line going through the scatterplot of your data, the residuals are the distances of of the points in the scatterplot from the best-fit line. If the model fits, then if you plot residuals against the fitted values, you should see random scatter.

In this case, the denominator of the Pearson residual will tend to understate the true variance of the \(Y_i\), making the residuals larger. creative depot blog https://joshtirey.com
