WebIn statistics, the phi coefficient (also referred to as the "mean square contingency coefficient" and denoted by ϕ or r ϕ) is a measure of association for two binary variables introduced by Karl Pearson. This measure is similar to the Pearson correlation coefficient in its interpretation. Web15. apr 2024 · We need to map the possible range of values for correlation coefficients, [-1, 1], to a color palette. We’ll use a diverging palette, going from red for -1, all the way to green for 1. Looking at Seaborn color palettes, seems that we’ll do just fine with something like sns.palplot (sns.diverging_palette (220, 20, n=7))
