ERROR 180-322: Statement is not valid or it is used out of proper order.

I am trying to use a backwards selection process to create a parsimonious model using proc logistic.

when I attempt it my code is this:

proc logistic data=test2;
class stroke(ref="1") / param=ref;
model prevhyp (event="1")= stroke diabetes sysbp educ BMI diabp totchol glucose prevchd;
selection=stepwise;
slentry=0.05
slstay=0.20
details
lackfit;
run;

and my SAS log says this:

248 proc logistic data=test2;
249 class stroke(ref="1") / param=ref;
250 model prevhyp (event="1")= stroke diabetes sysbp educ BMI diabp totchol glucose prevchd;
251 selection=stepwise;
---------
180
ERROR 180-322: Statement is not valid or it is used out of proper order.
252 slentry=0.05
253 slstay=0.20
254 details
255 lackfit;
256 run;

I am not sure what I am doing wrong as I have never used the SLSTAY function before.

Off the top of my head, SELECTION= is an option on the MODEL statement. The line before should not end with a semicolon.

Instead, change it to a slash to indicate that MODEL statement options follow.

Yes, @Astounding is correct, you have a semicolon where you need a / to specify options instead.

model prevhyp (event="1") = stroke diabetes sysbp educ BMI diabp totchol glucose prevchd /selection=stepwise ... <rest of your options>;
