Variable name truncation in GLMSELECT

bkq32 — Wed, 09 Sep 2020 23:12:21 GMT

Is there a way to prevent my variables names from being truncated to 20 characters in the output?

data have;
 set sashelp.bweight;
 rename momwtgain = dont_truncate_this_var;
run;


proc glmselect data = have;
 model weight = momage cigsperday dont_truncate_this_var;
run; quit;

My actual GLMSELECT statement uses stepwise selection and a CLASS statement, so I'd prefer to stick with GLMSELECT if possible.

What output? Are you saying that the print-out generated by PROC GLMSELECT is showing only the first 20 characters of that variable name? What part of the print-out?

Or are you generating an output dataset from that PROC? I don't see where you are specifying any output datasets in your code.

Sorry, yes the first option. I'm referring to the print-out from PROC GLMSELECT. In the SelectionSummary and ParameterEstimates results, the variable "dont_truncate_this_var" has been shortened to "dont_truncate_this_v". The log says:

NOTE: Effect labels on plots have been truncated at 20 characters.

Try option NAMELEN=
proc glmselect data = sashelp.class namelen=32;
model weight = age height;
run; quit;

This worked great, thank you!
