Boxplot of Youden Index (J) for all investigated approaches, different definitions of neighborhood (OR-rule and AND-rule) and sample sizes 50, 100, 200, 500 and 1000. Yellow marks the OR-rule and orange the AND-rule. Lasso - CV represents cross-validated optimal penalty, Lasso - AIC represents AIC optimal penalty, Lasso - BIC represents BIC optimal penalty, Bolasso - CV represents Bolasso with cross-validated optimal penalty and Bolasso - 90 represents a Bolasso with a cut of 90% and neighborhood size 10.
