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. " - Cox and snell r2

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 .
