Display a fitted line plot and residual plots for diagnosis of the regression model fit.
Plot of fitted line with data: Check to display a fitted line plot with the orthogonal fitted line. The orthogonal regression equation is shown on the plot.
Overlay least squares fitted line: Check to display the ordinary least squares fitted line on the plot for comparison. The ordinary least squares fit equation is shown on the plot.
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.
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.
