Residuals Plot

A plot of residuals versus the fitted values is known as the residuals plot.

There should not be any specific pattern in the residuals plot, such as:

i. trend: negative residuals observed at small predicted values and positive residuals observed at large predicted values, which would imply non-linearity;

ii. non-uniform spread: clustered residuals observed for small predicted values and dispersed residuals observed for large predicted values, which would imply heteroscedasticity.
