PLOT Subcommand (MLP command)

The PLOT subcommand indicates the chart output to display. If PLOT is not specified, then the default chart (the network diagram) is displayed. If PLOT is specified, then only the requested PLOT output is displayed.

NETWORK Keyword

The NETWORK keyword displays the network diagram. This chart is shown by default.

PREDICTED Keyword

The PREDICTED keyword displays a predicted-by-observed value chart for each dependent variable. For categorical dependent variables, a boxplot of predicted pseudo-probabilities is displayed. For scale dependent variables, a scatterplot is displayed.

  • Predicted-by-observed value charts are based on the combined training and testing samples or only the training sample if there is no testing sample.

RESIDUAL Keyword

The RESIDUAL keyword displays a residual-by-predicted value chart for each scale dependent variable. This chart is available only for scale dependent variables. The RESIDUAL keyword is ignored for categorical dependent variables.

  • Residual-by-predicted value charts are based on the combined training and testing samples or only the training sample if there is no testing sample.

ROC Keyword

The ROC keyword displays an ROC (Receiver Operating Characteristic) chart for each categorical dependent variable. It also displays a table giving the area under each curve in the chart.

  • For a given dependent variable, the ROC chart displays one curve for each category. If the dependent variable has two categories, then each curve treats the category at issue as the positive state versus the other category. If the dependent variable has more than two categories, then each curve treats the category at issue as the positive state versus the aggregate of all other categories.
  • This chart is available only for categorical dependent variables. The ROC keyword is ignored for scale dependent variables.
  • ROC charts and area computations are based on the combined training and testing samples or only the training sample if there is no testing sample.

GAIN Keyword

The GAIN keyword displays a cumulative gains chart for each categorical dependent variable.

  • The display of one curve for each dependent variable category is the same as for the ROC keyword.
  • This chart is available only for categorical dependent variables. The GAIN keyword is ignored for scale dependent variables.
  • Cumulative gains charts are based on the combined training and testing samples or only the training sample if there is no testing sample.

LIFT Keyword

The LIFT keyword displays a lift chart for each categorical dependent variable.

  • The display of one curve for each dependent variable category is the same as for the ROC keyword.
  • This chart is available only for categorical dependent variables. The LIFT keyword is ignored for scale dependent variables.
  • Lift charts are based on the combined training and testing samples or only the training sample if there is no testing sample.

NONE Keyword

The NONE keyword suppresses all PLOT output. This keyword may not be specified with any other PLOT keywords.
