Detailed Description

Member Function Documentation

◆ getValue()

int getValue ( )

Returns the value corresponding to the variable importance computation mode object identifier

Returns
Value corresponding to the variable importance computation mode object identifier

Member Data Documentation

◆ MDA_Raw

final VariableImportanceModeId MDA_Raw = new VariableImportanceModeId(MDA_RawId)
static

Mean Decrease Accuracy (permutation importance). For each tree, the prediction error on the out-of-bag portion of the data is computed (error rate for classification, MSE for regression). The same is done after permuting each predictor variable. The difference between the two are then averaged over all trees.

◆ MDA_Scaled

final VariableImportanceModeId MDA_Scaled = new VariableImportanceModeId(MDA_ScaledId)
static

Mean Decrease Accuracy (permutation importance). This is MDA_Raw value normalized by its standard deviation.

◆ MDI

final VariableImportanceModeId MDI = new VariableImportanceModeId(MDIId)
static

Mean Decrease Impurity. Computed as the sum of weighted impurity decreases for all nodes where the variable is used, averaged over all trees in the forest

◆ none

final VariableImportanceModeId none = new VariableImportanceModeId(noneId)
static
