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.
