Public Attributes
types::FeatureVector	permuted
types::FeatureVector	projections
types::FeatureVector	scale
types::FeatureVector	weighted_projections

Detailed Description

Grouped result of the three variable importance measures.

For single trees only projections and scale are populated; permuted and weighted_projections remain empty (size 0).

// Forest — all three measures:
auto vi1 = variable_importance_permuted(forest, x, y, seed: 0);
auto vi2 = variable_importance_projections(forest, x.cols());
auto vi3 = variable_importance_weighted_projections(forest, x, y);
 
// Single tree — projection-based only:
auto vi = variable_importance_projections(tree, x.cols());
