Dn |! (n22 + i)! Statistical Measures for Contrast Patterns 17 Smaller values of p are more desirable. When conducting significance tests for many contrast patterns, the issue of statistical correction for multiple testing arises. There are various approaches to this problem and a good discussion of the issues by Webb can be found in [430]. Mutual Information: This measures the information shared by the contrast pattern occurrence and the dataset label. It tells us how much knowing whether the contrast pattern occurs reduces our uncertainty about the dataset label and vice versa.
