The Binary Logistic, Multinomial Logistic, and Ordinal Regression procedures will print R^2 statistics (Cox & Snell, Nagelkerke, and McFadden). The next table includes the Pseudo R², the -2 log likelihood is the minimization criteria used by SPSS. We see that Nagelkerke’s R² is 0.409 which indicates that the model is good but not great. Cox & Snell’s R² is the nth root (in our case the 107th of the -2log likelihood improvement.

I believe it outputs the Nagelkerke R-square. Albert-Jan Binomial Logistic Regression using SPSS Statistics Introduction. A binomial logistic regression (often referred to simply as logistic regression), predicts the probability that an observation falls into one of two categories of a dichotomous dependent variable based on one or more independent variables that can be either continuous or categorical. Many pseudo R-squared models have been developed for such purposes (e.g., McFadden's Rho, Cox & Snell). These are designed to mimic R-Squared in that 0 means a bad model and 1 means a great model.

Therefore, the explained variation in the dependent variable based on our model ranges from 24.0% to 33.0%, depending on whether you reference the Cox & Snell R 2 or Nagelkerke R 2 methods, respectively. The next table includes the Pseudo R², the -2 log likelihood is the minimization criteria used by SPSS. We see that Nagelkerke’s R² is 0.409 which indicates that the model is good but not great.

The Aldrich-Nelson pseudo-R2 with the Veall-Zimmermann correction is the best approximation of the McKelvey-Zavoina pseudo-R2. Efron, Aldrich-Nelson, McFadden and Nagelkerke approaches severely underestimate the "true R2". Value.

SPSS will present you with a number of tables of statistics. Let’s work through and interpret them together. Again, you can follow this process using our video demonstration if you like.First of all we get these two tables (Figure 4.12.1):. Figure 4.12.1: Case Processing Summary and Variable Encoding for … 2Analogs. Several Pseudo R measures are logical analogs to OLS R 2 measures. McFadden’s R 2 2is perhaps the most popular Pseudo R of them all, and it is the one that Stata is reporting when it says Pseudo R2. However, fitstat also reports several over pseudo R^2 statistics. The formulas and rationale for each of these is presented in Appendix A 2016-08-03 R² is such a lovely statistic, isn't it?
