Cox & Snell’s R² is the nth root (in our case the 107th of the -2log likelihood improvement. SPSS reports the Cox-Snell measures for binary logistic regression but which produces the R 2 attributed to Nagelkerke (1991). But this Sir, I found your article very helpful. Actually i applied Binomial Logistic regression and I am getting cox and snell R2= .709 and nagelkerke R2= .959.

A generalized linear model, including cumulative links resp. multinomial models. Using SPSS for regression analysis Let us assume that we want to build a logistic regression model with two or more independent variables and a dichotomous dependent variable ( if you were looking at the relationship between a single variable and a dichotomous variable, you would use some form of bivarate analysis relying on contingency tables ). McKelvey and Zavoina (1975), Maddala (1983), Agresti (1986), Nagelkerke (1991), Cox and Wermuch (1992), Ash and Shwartz (1999), Zheng and Agresti (2000)). 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.

From the table above, we can conclude that based in Nagelkerke's R2, 42.3% of the variation in survival can be explained by the model including nationality, Model.

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. 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. A third type of measure of model fit is a pseudo R squared. The goal here is to have a measure similar to R squared in ordinary linear multiple regression. For example, pseudo R squared statistics developed by Cox & Snell and by Nagelkerke range from 0 to 1, but they are not proportion of variance explained.

Are high nagelkerke R2 values suspicious in a logistic regression model? Hi everyone, I'm running a logistic regression model with 5 independent variables (constructs) and 1 dichotomous dependent
I was also going to say 'neither of them', so i've upvoted whuber's answer. As well as criticising R^2, Hosmer & Lemeshow did propose an alternative measure of goodness-of-fit for logistic regression that is sometimes useful.
