Percent of concordant using proc genmod

[Demographer]

Hi,

When performing a logit regression with proc logisitic, an output showing the percent of concrodant and discordant is generated. Is it possible to get a similar one with proc genmod?

Association of Predicted Probabilities and Observed Responses
Percent Concordant	77.6	Somers' D	0.554
Percent Discordant	22.2	Gamma	0.555
Percent Tied	0.2	Tau-a	0.272
Pairs	418103514	c	0.777

GENMOD does not provide this since it fits a much wider range of model types than just logistic models. However, you can always fit the model in GENMOD (or other procedures) and then use the predicted probabilities in PROC LOGISTIC to get the table. See this note which illustrates it.
