Inmodel/outmodel in Proc Logistic

How to interpret the outmodel dataset? I want to replicate the outmodel in Python. Please share if there is any good article/link on this topic.

Outmodel creates a proprietary binary file that will be useless. The parameter estimates tables has enough for you to code it in Python using basic math.

FYI - SAS Enterprise Miner does port models in PMML or it used to. Not sure if any Python packages support that.

Is there any option to get the parameter estimates?

ods output parameterestimates=want;

Put that in your proc and the parameterestimates will be saved to a data set called WANT.

This is what I tried and didn't work:

ods output parameterestimates=want;

proc logistic
inmodel=abc
score
data=xyz
out=aaa
quit;

ods output close;

You can't use

ods output parameterestimates=want;

and INMODEL together. This particular ODS OUTPUT statement is for when you fit a model using PROC LOGISTIC, with no INMODEL=.
