R-square is similar R-square in PROC REG. but it is not AUC -- C statistic

```
proc logistic data=sashelp.class;
model sex=weight height/lackfit rsquare;
run;
```

Hello, is there an R-square in logistic regression? Is this the best goodness of fit or which goodness of fit is better to use?

There are a number of different model fit statistics available. It also depends on exactly which procedure as several do logistic regression and the nature of your data: Rsquare -2 Log Likelihood, AIC SC Homer-Lemeshow test are some available in Proc Logistic for tests/metrics. Look at the MODEL options.
