Model selection with proc surverylogistic

ChuksManuel — Fri, 03 Jul 2020 21:38:19 GMT

Hello programmers,

I am very familiar with using the SELECTION= option in sas in order to perform forward, backward or stepwise model selection.

However, is anyone aware if i can do this in proc survey logistic? If so, any referral to SAS documentation and syntax will be helpful.

This document did not address model selection in proc survey logistic....and i could not find any yet.

Thanks

What version of SAS/STAT do you have? You're referencing 13.1 there which is older.
You can check by running the following:

proc product_status;run;

From the latest documentation model selection does not appear to be a feature included:
https://documentation.sas.com/?docsetId=statug&docsetTarget=statug_surveylogistic_syntax12.htm&docsetVersion=15.1&locale=en

My suggestion was going to be use surveyreg and do the logistic regression the 'manual' way but it appears that it's not in that proc either 😞
