PROC GLM

[arodriguez]

Hi everyone and thanks for read it,

I am trying to calculate the treatment effect with the next prog glm.

     proc glm data=_aux_;

     class treatmentn /ref=FIRST;

     model _change = treatmentn /solution clparm;

     lsmeans treatmentn / pdiff=all CL stderr TDIFF adjust=bonferroni;

     run;

          quit;

For the unadjusted treatment effect I use the model, and for the adjusted I use it lsmeans.

The problem is that when I try to put ref='1'  it give me error

ERROR 22-322: Syntax error, expecting one of the following: FIRST, LAST.

ERROR 76-322: Syntax error, statement will be ignored.

and ref='level' must be a valid value. Any idea?

Thanks for the help,

  Toni

Try:

class treatmentn(ref='1');

The global options (after the slash options) are only FIRST and LAST.  A formatted value has to be directly associated with the variable.

Yes, it seems to work.

Thank you a lot.
