Draw five different residual plots for regular, standardized, or deleted residuals.

Dialog box items

Residuals for Plots You can specify the type of residual to display on the residual plots.

Regular: Choose to plot the regular or raw residuals.

Standardized: Choose to plot the standardized residuals.

Deleted: Choose to plot the Studentized deleted residuals.

Residual Plots

Individual plots: Choose to display one or more plots.

Histogram: Check to display a histogram of the residuals.

Normal plot: Check to display a normal probability plot of the residuals.

Residuals versus fits: Check to plot the residuals versus the fitted values.

Residuals versus order: Check to plot the residuals versus the order of the data in the run order column. The row number for each data point is shown on the x-axis-for example, 1 2 3 4... n.

Four in one: Choose to display a layout of a histogram of residuals, a normal plot of residuals, a plot of residuals versus fits, and a plot of residuals versus order.

Residuals versus variables: Check to display residuals versus selected variables, then enter one or more columns. Minitab displays a separate graph for each column.
