Visual Illustration For Proc Logistic

Hi everyone,

This is more stats-related question than a technical SAS-coding question, but maybe there is an option in the proc logistic procedure to generate the output I'm looking for.

I used a logistic regression model, proc logistic procedure, to model the probability of a binary event occuring (=1):

Event_ID	Probability/ Expected	Actual/ Event_Occured
123	0.98	1
223	0.67	1
224	0.012	1
225	0.0506	1
321	0.0006	0
322	0.103	0
323	0.0089	0
342	0.46	1
564	0.69	1
597	0.89	1
598	0.76	1
601	0.0045	0
689	0.15	0
756	0.68	1
897	0.72	1
899	0.089	0
1001	0.23	0
1501	0.88	1
8997	0.45	1

Is there an efficient way to graph the expected (predicted probabilities) vs actual (event results) to give an indication on how well the model is performing ?

Thank you !

Yes, use the EFFECTPLOT statement:

ods graphics on;
proc logistic data=sashelp.class;
model sex = height;
effectplot;
run;
