Field Detail

own_fields

public static java.lang.String[] own_fields

ntrees

public int ntrees

Number of trees in model

treeStats

public TreeStats treeStats

More indepth tree stats

r2

public double r2

r2 metric on validation set: 1-(MSE(model) / MSE(mean))

mse_train

public double[] mse_train

Train and validation errors per-tree (scored). Zero index is the no-tree error, guessing only the class distribution. Not all trees are scored, NaN represents trees not scored.

mse_valid

public double[] mse_valid

cm

public hex.ConfusionMatrix cm

Confusion Matrix for classification models, or null otherwise

auc

public hex.AUC auc

AUC for binomial models, or null otherwise

varimp

public hex.VarImp varimp

Variable Importance, if asked for
