I am running a logistic regression model in SAS base and while i am able to obtain a CTABLE for the training set , I cant seem to find how i will get it when scoring the validation set for the validation set
What is missing int he below code so i can obtain the CTABLE for the validation set and see where the optimal cut off point is?
PROC LOGISTIC INMODEL=MODELPARAMETERSTRAINING ;

Sorry, I don't know much beyond the basics of proc logistic. I mostly use proc dmreg within Enterprise Miner.
Not sure how to get the option you need, but a workaround would be to use the Score statement in proc logistic to score your validation set.
More info about proc logistic score statement here: https://support.sas.com/documentation/cdl/en/statug/63033/HTML/default/viewer.htm#statug_logistic_se...
I hope it helps!

Realised that i can do the computations by myself using the out roc, thank you for the information though

@chemicalab Can you please help me with the code on how we can get the classification table for validation data. Below is my code.
proc logistic data=training outmodel=newsModel;
model subs=sex age / link=glogit ctable outroc=d;
score data=training out=Score2;
proc logistic noprint inmodel=newsModel;
score data=validation out=ScoredTest;
proc print data=ScoredTest label noobs;
