Tschprow’s coefficient of association formula
Webcoefficient does not have a clear "variance explained" interpretation. Like other forms of correlation and association, eta cannot prove causal direction, only measure its level given the researcher's Webφ (phi coefficient) The phi coefficient is a measure of association between two binary variables introduced by Karl Pearson, and is related to the chi-squared statistic of a 2x2 contingency table. In machine learning terms, a contingency table is basically the same as the confusion matrix.
