Problems with code (in the do loop?) for proc logistic MC exact estimate

gillgiff — Sat, 15 Feb 2014 01:06:55 GMT

I am trying to run a logistic regression using a hybrid MC exact estimation technique. There appears to be something wrong with my code and I think it is in the do loop. I am brand new to the SAS language and someone provided me with the following sloppy code.

I was trying to run the analysis in SAS Enterprise Guide with SAS version 9.3. Apparently this code worked in a previous or later version of SAS. Any obvious mistakes with the code? The data is a binary response of two different count techniques with the actual paired counts as predictors.

Sincerely, Gifford Gillette

data Data1;

do ID=1 to 16;

do Outcome = 1 to 0 by -1;

input rnam Count @@;

Works fine in SAS/STAT 12.1 (SAS 9.3 TS1M2). - PG

PGStats,

Hmmm.....

Any chance you could run this similar code and email me the results? I have a feeling our University SAS version needs updated.

data Data1;

do ID=1 to 12;

do Outcome = 1 to 0 by -1;

input rnam Count @@;

output;

I don't see anything wrong with the data step code, but I did notice that OUTCOME and RNAM always have the same value.
