How to graph logits using categorical variable for logistic regression in SAS university edition?

Proto — Wed, 04 Jul 2018 12:51:40 GMT

Hi,

I was given code for SAS 9.4 to graph the logits for categorical variable using the gplot procedure (below) but because I'm using SAS university edition that procedure will not work. Any ideas how I can modify this so I can get that output? Thanks

proc means data=zero noprint nway;
class Q15;
var access;
output out=bins sum(access)=acess;
run;

data bins;
set bins;
logit=log((access+1)/(_freq_-access+1));
run;

goptions reset=all;
proc gplot data=bins;
plot logit*Q15;
symbol h=1.5 v=dot i=none;
title 'estimated logit plot of gender';
run;
quit;

Use PROC SGPLOT instead. The syntax is pretty simple.

For a great introduction to PROC SGPLOT check out the Getting Started with SGPLOT series at the Graphically Speaking blog

And SAS does effect plots from logistic regression that are quite helpful.

SAS/GRAPH and GPLOT/GCHART do not work in SAS UE. SG procedures is available and produces better quality graphics + easier to use.

A lot of SAS references to GPLOT/GCHART will be older as SG procedures were introduced later and SAS is pretty old.
