Cumulative Validation

In the Boosted Tree platform, the Cumulative Validation report shows a plot of the fit statistics for the Validation set versus the number of layers. This report is available only if validation is used.

For a continuous response, the single fit statistic is R-Square. For a categorical response, the fit statistics are listed below and are described in Measures Report.

• R-Square (Entropy R-Square)

• Avg - Log p (Mean - Log p)

• Root Average Squared Prediction Error (RASE)

• Avg Abs Error (Mean Abs Dev)

• MR (Misclassification Rate)

The Cumulative Details report below the Cumulative Validation plot gives the values used in the plot.
