Stat > Time Series > ARIMA > Graphs

Displays a time series plot and various residual plots. You do not have to store the residuals in order to produce these plots.

Dialog box items

Time series plot (including optional forecasts): Check to display a time series plot of the series. When you use the ARIMA - Forecasts subdialog box to generate forecasts, Minitab displays the forecasts and their 95% confidence limits on the plot.

Residual Plots

ACF of residuals: Check to display an autocorrelation function for the standard or raw residuals. The graph includes critical value lines at + two standard errors.

PACF of residuals: Check to display a partial autocorrelation function for the standard or raw residuals. The graph includes critical value lines at + two standard errors.

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.
