variableImportance {drf}

Variable importance based on MMD

Description

compute an mmd-based variable importance for the drf fit.

Usage

variableImportance(
  object,
  h = NULL,
  response.scaling = TRUE,
  type = "difference"
)

Arguments

object

an S3 object of class drf.

h

the bandwidth parameter, default to NULL using then the median heuristic.

response.scaling

a boolean value indicating if the responses should be scaled globally beforehand.

type

the type of importance, could be either "raw", the plain MMD values, "relative", the ratios to the observed MMD or "difference", the excess to the observed MMD

Value

a vector of variable importance values.
