These statistics, which are usually identical to the standard R2 when applied to a linear model, generally fall into categories of entropy-based and variance-based (Mittlb ock and Schemper Thanks David for your response.

Dear R community. I´m working with a generalized linear model which the response variable is a categorical one and the predictive variables are weather conditions.

Although SPSS does not give us this statistic for the model that has only the intercept, I know it to be 425.666 (because I used these data with SAS Logistic, and SAS does give the -2 log likelihood.

Nagelkerke’s R2 is part of SPSS output in the ‘Model Summary’ table and is the most-reported of the R- squared estimates. In this case it is 0.737, indicating a moderately strong relationship of 73.7% between the predictors and the prediction. As I understand it, Nagelkerke’s psuedo R2, is an adaption of Cox and Snell’s R2. The latter is defined (in terms of the likelihood function) so that it matches R2 in the case of linear regression, with the idea being that it can be generalized to other types of model. There is a simple correction, and that is to divide R2C&S by its upper bound, which produces the R2 attributed to Nagelkerke (1991). But this correction is purely ad hoc, and it greatly reduces the theoretical appeal of the original R2C&S. 2. There is no glossary: If you are using SPSS; and especially running logistic regression models, you should probably already know what a -2LL and the difference between the Cox & Snell R2 and Nagelkerke R2. The next table includes the Pseudo R², the -2 log likelihood is the minimization criteria used by SPSS.
