ROC

ROC is available in Statistics Base Edition.

Note: Version 29.0.1 onwards, the menus and dialogs for ROC command are removed and this command is available as syntax only.

ROC produces a receiver operating characteristic (ROC) curve and an estimate of the area under the curve.

ROC varlist BY varname({varvalue  })
                       {‘varvalue’}

[/MISSING = {EXCLUDE**}]
            {INCLUDE  }

[/CRITERIA = [CUTOFF({INCLUDE**})] [TESTPOS({LARGE**}) [CI({95** })]
                     {EXCLUDE  }            {SMALL  }      {value}

             [DISTRIBUTION({FREE** })]]
                           {NEGEXPO}

[/PLOT = [CURVE**[(REFERENCE)]] [NONE]]

[/PRINT = [SE][(MODELQUALITY)] [COORDINATES]].

** Default if subcommand is omitted.

The old ROC Curve procedure supports the statistical inference about a single ROC curve. This may also be recovered by the new ROC Analysis procedure. Furthermore, the new ROC Analysis procedure can compare two ROC curves generated from either independent groups or paired subjects.

This command reads the active dataset and causes execution of any pending commands. See the topic Command Order for more information.

Syntax for the ROC command can be generated from the ROC Curve dialog box.
