Results of the null case study – variable selection frequency. Mean variable selection frequencies for the null case, where none of the predictor variables is informative. The plots in the top row display the frequencies when the randomForest function is used, the bottom row when the cforest function is used. The left column corresponds to bootstrap sampling with replacement, the right column to subsampling without replacement.
