Error: File work.data does not exist

[gioitran]

Hello,

I am learning modified poisson regression and stopped in the middle due to the error: work.data does not exist. My code is:

proc genmod data=out1 DESCENDING;
class b6_3c a24_6c;
model had_2c = a1 b6_3c a24_6c/dist=poisson link=log;
repeated subject=b6_3c/type=unstr;
ods output GEEEmpPEst=est;
run;

data estimate;
set est;
if Parm ='b6_3c';
run;

ERROR: File WORK.EST.DATA does not exist.

I could not tell what happened and really need your help.

Thank you very much

George

Thank you very much Kurt for your response. 

I saw message about issufficient memory. I used Mackbook pro 2015 so not sure it is the reason or not.

I am learning to generate prevalence ratio instead of odds ratio.

Best

Add this statement - options fullstimer; - at the top of your program and rerun it. It will then report on memory usage. Please post this log.

Please see the new log with your option.

As you can see SAS is using all available memory of around 2GB. Are you using 32 or 64-bit SAS on your PC? Only 64-bit SAS can go beyond around 2GB. How much memory does your PC have? Also please post the log from this:

proc options option = memory;
run;

[gioitran]

I used SAS 64 bit for window, X64_10PRO platform. I run option =memsize as it did not accept option=memory.

239  proc options option = memsize;
240  run;

    SAS (r) Proprietary Software Release 9.4  TS1M4

 MEMSIZE=2147483648
                   Specifies the limit on the amount of virtual memory that can be used during a
                   SAS session.

Sorry, should have been this:

proc options group = memory;
run;

You didn't say how much memory your PC has. You could try setting - MEMSIZE = 8GB - which has to be done in your SAS CONFIG file or as a command line option. 

[gioitran]

Sorry for missing infor. My Mac pro memory is 8GB (1867 MHz) with processor 2.9 HGz dual core intel core I5.

I run SAS on window so don't know it affects memory or not. 

I will try to reset memory for SAS

Thank you

How much memory is assigned to the virtual windows environment?
