proc reg error

I am running a programme which includes several thousand regressions and I need the ods outputs.. The programme has failed twice with the following log

It looks to me like some sort of memory overflow - could you reduce the amount of data you're passing through? If that doesn't fix it or you can't do it then I think you'll have to raise a track with SAS Support which you can do here http://support.sas.com/ctx/supportform/createForm

thanks. I've put an extra loop into my macro so that it executes the proc reg in smaller chunks of data, to see if that will work

Try to use BY statement of PROC REG .

Re: proc reg error

thanks for the link, it will come in useful for future. I think I've worked around the problem by analysing smaller chunks of data for now.

You should "contact technical support and provide them with the following traceback information" in addition to your SAS version, operating system, and program.  


AS KSharp said, you probably want to use BY-group processing for this problem, rather than a macro loop. And make sure that you use ODS GRAPHICS OFF. Also use NOPRINT or ODS EXCLUDE ALL to suppress the SAS output.

Re: proc reg error

thanks, I'll send that through. I have managed a temporary fix by analysing smaller chunks of data.. (a lazy way out, I know). I can't use noprint as I need the ods tables output.

But you can still use 

ODS EXCLUDE ALL;

proc reg;

..

ODS OUTPUT TableName=DataSetName;

quit;

ODS EXCLUDE NONE;

 

to suppress output to the open ODS destinations (eg, HTML or LISTING)

Please post your SAS program. We might be able to offer a more efficient solution.

I am doing many regressions of LINFLUX against the same variable (ETIM), which is timeseries data, but moving the time window that the model starts for each observation, hence the loops
