21 Feb 2004 Nagelkerke's R-square, which is provided by SPSS in this section. • Likelihood Ratio Tests. Provides the likelihood ratio tests for the IVs.

SPSS Statistics Example. A health researcher wants to be able to predict whether the "incidence of heart disease" can be predicted based on "age", "weight", "gender" and "VO 2 max" (i.e., where VO 2 max refers to maximal aerobic capacity, an indicator of fitness and health). To this end, the researcher recruited 100 participants to perform a maximum VO 2 max test as well as recording their age

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. 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.

Notice how the two versions (Cox & Snell and Nagelkerke) do vary! 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. Nagelkerke R2 is a modification of Cox & Snell R2, the latter of which cannot achieve a value of 1.

Mer lättolkade är de två Pseudo-R2-måtten vi får ut, ”Cox & Snell R Square” och ”Nagelkerke R Square”. The next table includes the Pseudo R², the -2 log likelihood is the minimization criteria used by SPSS.

The appearance of these screen shots will be slightly different than Nagelkerke.

Logistic regression does not have an equivalent to the R-squared that is found in OLS regression; however, many people have tried to come up with one. There are a wide variety of pseudo-R-square statistics (these are only two of them).

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. Adding the gender variable reduced the -2 Log Likelihood statistic by 425.666 - 399.913 = 25.653, the χ I demonstrate how to perform a binary (a.k.a., binomial) logistic regression. The data were simulated to correspond to a "real-life" case where an attempt is R2: Nagelkerke's R squared. 参考文献 References.
