Stats: What is a phi coefficient? - PMean
In statistics, the phi coefficient (or mean square contingency coefficient and denoted by φ or rφ) is a measure of association for two binary variables. In machine learning, it is known as the Matthews correlation coefficient (MCC) and used as a measure of the quality of binary (two-class) classifications, introduced by … Visa mer Although computationally the Pearson correlation coefficient reduces to the phi coefficient in the 2×2 case, they are not in general the same. The Pearson correlation coefficient ranges from −1 to +1, where ±1 indicates perfect … Visa mer The Matthews correlation coefficient has been generalized to the multiclass case. This generalization was called the $${\displaystyle R_{K}}$$ statistic (for K different classes) by … Visa mer • Cohen's kappa • Contingency table • Cramér's V, a similar measure of association between nominal variables. • F1 score Visa mer The MCC is defined identically to phi coefficient, introduced by Karl Pearson, also known as the Yule phi coefficient from its introduction by Udny Yule in 1912.
