Gamma measure of association
WebApr 1, 2011 · This has an associated measure of association, the WMW odds, related to Agresti’s generalized odds ratio. Both for rank correlation coefficients and WMW odds confidence intervals can be calculated. I find odds more intuitive, otherwise I believe both kinds of measures are appropriate. Share Cite Improve this answer Follow WebGoodman-Kruskal gamma (γ) shows how many more concordant than discordant pairs exist divided by the total number of pairs excluding ties. Use the Goodman-Kruskal gamma to measure the association between the ordinal variables. Perfect association exists when γ = 1. In ordinal and binary logistic regression, if X and Y are independent, then γ = 0.
