WebFeb 20, 2024 · In this letter, we present details on how to derive R2using the reported C statistic (AUROC) for such existing prediction models with a binary outcome. The C … R N, proposed by Nico Nagelkerke in a highly cited Biometrika paper, provides a correction to the Cox and Snell R so that the maximum value is equal to 1. Nevertheless, the Cox and Snell and likelihood ratio R s show greater agreement with each other than either does with the Nagelkerke R . Of course, this might not be the case for values exceeding 0.75 as the Cox and Snell index is capped at this value. The likelihood ratio R is often preferred to the alternatives as it is most ana…

I simulate four independent variables and specify that each logit coefficient should be of size log (2)=0.69. This works nicely, the explained variance (I report Cox & Snell's r2) is 0.34.
