Time series plot (including optional forecasts)

Display plot: Choose to display the  time series plot.

Do not display plot: Choose to suppress the time series plot.

Residual Plots

Individual plots:  Choose to display one or more plots.

Histogram of residuals: Check to display a histogram of the residuals.

Normal plot of residuals: 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. 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 the variables: Enter one or more columns containing the variables against which you want to plot the residuals. Minitab displays a separate graph for each column.
