predictiveness_point_est: Estimate a nonparametric predictiveness functional

Description

Compute nonparametric estimates of the chosen measure of predictiveness.

Usage

predictiveness_point_est(
  fitted_values,
  y,
  weights = rep(1, length(y)),
  type = "r_squared",
  na.rm = FALSE
)

Arguments

fitted_values

fitted values from a regression function.

y

the outcome.

weights

weights for the computed influence curve (e.g., inverse probability weights for coarsened-at-random settings)

type

which parameter are you estimating (defaults to anova, for ANOVA-based variable importance)?

na.rm

logical; should NA's be removed in computation? (defaults to FALSE)

Value

The estimated measure of predictiveness.

Details

See the paper by Williamson, Gilbert, Simon, and Carone for more details on the mathematics behind this function and the definition of the parameter of interest.
