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.

final VariableImportanceModeId MDA_Scaled = new VariableImportanceModeId(MDA_ScaledId)
static

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

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

final VariableImportanceModeId none = new VariableImportanceModeId(noneId)
static
