I'm using a multinomial logit model to study a large dataset, approximately 700.000 observations. In particular I have 700.000 observations divided in 23 classes at time 1, and each one evolves in the same or a different class of this at time 2. So, with proc logistic with link multilogit I'm trying to estimate the probability that an observation in the class i at time 1 goes to class j at time 2( also j=i is accetable). Here is the code:
PROC SORT DATA=Finalall OUT=Dieci_undici ;
BY _2010;
RUN ;
proc logistic data=Dieci_undici; by _2010;
model _2011=SHP_AREA / link=glogit;
quit;
And it works. Buf if I add this line:
output pred = predicted predprobs = i;
Then I have the following problem :
"OUT OF RESOURCES Select"
-R. Retry
-N Tell procedure/DATA step no more resources
-C Cancel Submitted Statement
- T. Terminate SAS
What is wrong?
Thank you very much for your help.
