Summarize Bootstrap Subgroup Analysis Results

Comprehensive summary of bootstrap subgroup identification results including basic statistics, factor frequencies, consistency distributions, and agreement with the original analysis subgroup.

Usage

summarize_bootstrap_subgroups(results, nb_boots, original_sg = NULL, maxk = 2)

Arguments
