Specifically, it is calculated as the Cox & Snell R2 divided by one minus the likelihood of the null model raised to the power of 2/n. Values closer to one indicate that the specified model outperforms the null model.

WebCox-Snell’s R squared (“generalized” R squared) Cox-Snell’s R squared uses the likelihood (as opposed to the log-likelihood), so some additional mathematical manipulation would be required to calculate this value. Unlike other pseudo R squared values here, the maximum of Cox-Snell’s R squared is less than 1. WebThe Cox-Snell R2 (both corrected and uncorrected) was actually discussed earlier by Maddala (1983) and by Cragg and Uhler (1970). Cox-Snell is the optional R2 reported by PROC LOGISTIC.
