Histogram of the distribution of the classification accuracy (bars; left axis) and p-values from the permutation test (for accuracy > .5; dots; right axis) for 10,000 simulations with 100 trials, 40 features, 10 × 10-fold cross-validation. The vertical thick line illustrates the binomial test lower bound and the horizontal thick line shows the permutation test accuracy level at p < .05.
