PLOT Subcommand (ROC ANALYSIS command)

The PLOT subcommand plots the ROC and precision-recall (PR) curves.

CURVE=ROC

Creates the ROC curve chart. Use (REFERENCE) to draw a diagonal reference line on the resulting chart. This is the default setting.

CURVE=PR

Creates the PR curve chart. Use (REFERENCE) to draw a diagonal reference line on the resulting chart.

Note: Specify CURVE = ROC PR to create both the ROC and PR curve charts.

CURVE=NONE

Plotting is suppressed, and no chart is created.

PRINTERPOLATE=TP

Specifies that stepwise interpolation, along with the true positives, is used as the interpolation method for the PR curve. This is the default setting.

PRINTERPOLATE=FP

Specifies that PR curve interpolation is made along the false positives.

MODELQUALITY=FALSE

A bar chart is not created. This is the default setting.

MODELQUALITY=TRUE

A bar chart is created to display the value of the lower bound of the confidence interval of the estimated area under the curve.
