Select the residual plots to generate. This button is inactive unless you selected a linear model to fit from the Analysis sub-dialog box.

Residuals for Plots

Specify the type of residuals to display on the residual plots. For more information, go to Which types of residuals are included in Minitab?.

Regular: Use regular residuals in residual plots.
Standardized: Use standardized residuals in residual plots.
Deleted: Use deleted residuals in residual plots.

To use the ln residuals for a linear model for the standard deviation, go to the Options sub-dialog and specify to use Use ln(s) for all standard deviation output.

Residual Plots

Use residual plots to examine whether your model meets the assumptions of the analysis. For more information, go to Residual plots in Minitab

Individual plots: Select the residual plots that you want to display.

Histogram

Display a histogram of the residuals.

Normal plot

Display a normal plot of the residuals.

Residuals versus fits

Display a plot of the residuals versus the fitted values.

Residuals versus order

Display a plot of the residuals versus the order of the data.
Four in one: Display all four residual plots together in one graph.

Residuals versus variables

Enter one or more variables to plot versus the residuals. You can plot the following types of variables:

Variables that are already in the current model.
Important variables that are not in the current model, to determine whether they are related to the response.
