ppforest2::VariableImportance Struct Reference

Grouped result of the variable importance measures. More...

#include <Evaluation.hpp>

Public Attributes
types::FeatureVector	permuted
	VI1 — per-variable permuted importance (forest only).
types::FeatureVector	projections
	VI2 — per-variable projection-coefficient importance.
types::FeatureVector	scale
	Per-variable σ used to rescale coefficients (columnwise sd).
types::FeatureVector	weighted_projections
	VI3 — per-variable weighted-projection importance (forest only).

Detailed Description

Grouped result of the variable importance measures.

Produced by the variable_importance(...) overloads below. variable_importance(Tree) fills projections and scale; variable_importance(Forest) fills all four fields. Individual measures can be computed via vi_projections, vi_permuted, and vi_weighted_projections directly.
