Scoring utility

Source: R/scoring.R
compute_score_relation.Rd

Computes the relation of score before a change (e.g. permutation, LOCO, ...) and after.

Usage

compute_score_relation(
  scores_pre,
  scores_post,
  relation = "difference",
  minimize = TRUE
)

Arguments

scores_pre

(numeric()) Score before change.

scores_post

(numeric()) Score after change.

relation

(character(1), "difference") Either "difference" or "ratio".

minimize

(logical(1), TRUE) Whether the score needs to be minimized (e.g. RMSE) or maximized (e.g. AUC).

Value

A numeric vector of the same length as scores_pre and scores_post

Details

If minimize == TRUE, then scores_post - scores_pre is computed for relation == "difference", otherwise scores_pre - scores_post is given.

Examples


pre = rnorm(10)
post = pre + runif(10)

compute_score_relation(pre, post)
