I want to calculate "Association of Predicted Probabilities and Observed Responses" (that is Somer's S, Karuskal Gamma and Kendall's Tau) for logistic regression model. How can I find these using STATA or SPSS?
I suggest you download -somersd- from within Stata (type: ssc install somersd). Additionally, there are several papers that Roger Newson wrote to accompany the somersd package (he wrote somersd). This is a straightforward program that should allow you to answer (non-parametrically) a large array of study questions
