PLOT Subcommand (DISCRIMINANT command)

PLOT requests additional output to help you examine the effectiveness of the discriminant analysis.

• If PLOT is specified without keywords, the default is COMBINED and CASES.
• If any keywords are requested on PLOT, only the requested plots are displayed.
• If PLOT is specified with any keyword except MAP, DISCRIMINANT displays a classification processing summary table and a prior probabilities for groups table.

COMBINED. All-groups plot. For each case, the first two function values are plotted.

CASES(n). Casewise statistics. For each case, classification information, squared Mahalanobis distance to centroid for the highest and second highest groups, and discriminant scores of all functions are plotted. Validated statistics are displayed for selected cases if CROSSVALID is specified on STATISTICS. If n is specified, DISCRIMINANT displays the first n cases only.

MAP. Territorial map. A plot of group centroids and boundaries used for classifying groups.

SEPARATE. Separate-groups plots. These are the same types of plots produced by the keyword COMBINED, except that a separate plot is produced for each group. If only one function is used, a histogram is displayed.

ALL. All available plots.
