Cramer's v检验
WebSep 30, 2024 · Cramer’s V is a measure of the strength of association between two nominal variables. It ranges from 0 to 1 where: 0 indicates no association between the two variables. 1 indicates a perfect association between the two variables. It is calculated as: Cramer’s V = √(X2/n) / min (c-1, r-1) where: X2: The Chi-square statistic.
