Question about "proc mixed"

Hi!

 

I'm trying to use "proc mixed" for a data set with about 8 million records. The analysis was taking too long and I was wondering why. Finally, it stopped and I got an error message saying SAS stopped processing because of insufficient memory. The warning statement in the log said "class level for ID are not printed because of excessive size." My question is: is there a way to avoid the subject IDs from being printed?

 

Here's the code I'm trying to use:

 

proc mixed data = enews

PLOTS (ONLY) = BOXPLOT

METHOD=REML;

CLASS trt time ID;

MODEL new_click = trt time trt*time / HTYPE=3

SOLUTION

CL

ALPHA = 0.1

DDFM=BETWITHIN

;

RANDOM ID / SUBJECT=ID TYPE=VC;

;

LSMEANS trt time trt*time / PDIFF=ALL ADJUST=BON;

RUN;
