However, to evaluate the goodness-of-fit of logistic models, several pseudo R-squareds have been developed. These are "pseudo" R-squareds because they look like R-squared in the sense that they are on a similar scale, ranging from 0 to 1 …

It is given by: Visa mer 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 … Visa mer A word of caution is in order when interpreting pseudo-R statistics. The reason these indices of fit are referred to as pseudo R is that they do not represent the proportionate reduction in error as the R in linear regression does. Linear regression assumes Visa mer
