Hello - what does one use for R-square in logistic regression...is it AUC?
R-square is similar to R-square in PROC REG. but it is not AUC (c) statistic
proc logistic data=sashelp.class;
model sex=weight height/lackfit rsquare;
run;
From ballardw:
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, Hosmer-Lemeshow tests are some available in Proc Logistic for tests/metrics. Look at the MODEL options.
