How to use the store statement in proc surveylogistic

[Estee]

Hi,

I am running a logistic regression for survey data using proc surveylogistic. I wanted to save the model so that I could obtain predicted values for all subjects in a different dataset.

Here's my issue:

I'm using the store statement in proc surveylogistic to store the model info. I am also using the Domain statement in proc surveylogistic which gives me an overall analysis, an analysis for TAG = 0, and another analysis for TAG = 1.

If the model outputs 3 regression models, how does the store statement work? Does it store all 3 models? Just one? When I run a dataset through proc plm and use this model, can I specify which model I want it to use?

Here's an example of what my code looks like: 

proc surveylogistic data= dir.DF1;
WEIGHT WT ;
CLUSTER hosp;
STRATA stratum_key;
Class GainCAT3 (ref = "1")
/param = ref;
Model CSection(event='1') = GainCAT3 ;
Domain TAG;
store dir.Model;
run;

proc plm restore = dir.Model;
score data = NewData out = dir.pred predicted lcml uclm/ ilink;
run;

Any help is appreciated.

Thank you.

There is only one model, which contains the parameter TAG. When you score the data, the procedure looks to see whether TAG=0 or 1 or 2 and uses the appropriate formula.
