run time error for linear regression

student2 — Sun, 20 Mar 2016 19:23:28 GMT

I'm not sure what this "run time error" means on SAS Enterprise Miner 14.1? On the log it says: " ERROR: Run time error was encountered. The system error returned was 1016. Please report unresolved problems to Technical Support."

Can you do a Find of "ERROR:" in the the log from the Regression node and paste in that section?

Hi,

I pasted the error message below:

ERROR: The SAS System stopped processing this step because of insufficient memory.
WARNING: The data set EMWS1.REG_EMESTIMATE may be incomplete. When this step was stopped there were 0 observations and 0 variables.
WARNING: The data set EMWS1.REG_OUTTERMS may be incomplete. When this step was stopped there were 0 observations and 0 variables.
WARNING: The data set EMWS1.REG_MAPDS may be incomplete. When this step was stopped there were 0 observations and 0 variables.

I can't see your the PROC DMREG code that is run from what you attached (I assume that is right above the errors you reported), but a likely culprit is that when the procedure tries to build the X'X matrix, there are either too many inputs or some input
variables that contain many levels and thus will make the procedure run
out of memory. Can you see in the variables editor if there are any inputs marked as ordinal or nominal that have a large number of levels?

Also are you using a selection method? Using stepwise or forward selection might help.

Thank you for your help. I realized that some of my variables had too many levels and it was eating up all the memory.
