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.     ... View more
