Plot cross-validation ranking stability

Produces a bar chart of either the top-1 selection frequency or the mean CV rank for each candidate model.

Usage

plot_cv_stability(cv_obj, metric = c("top1_frequency", "mean_rank"))

Arguments

cv_obj

A list returned by cv_ranking_stability.

metric

Character string. One of "top1_frequency" (default) or "mean_rank".

Value

Invisibly returns NULL; called for its side effect.

Examples

models <- list(m1 = mpg ~ wt + hp, m2 = mpg ~ wt + hp + disp)
cv_obj <- cv_ranking_stability(models, mtcars, v = 5, R = 20)
plot_cv_stability(cv_obj, metric = "top1_frequency")
