发帖数: 2007 | 1 Suppose that I have a data set data1, with numerical variables
x, y, z. I would like to do regression y=x if a macro
variable is "a" and do z=x y if the macro variable is not
"a". The following does not work well. How to do it?
%macro regre(var);
%if "&var."="a" %then %do;
proc reg data=data1;
model y=x;
run;
%end;
%else %do;
proc reg data=data1;
model z=x y;
run;
%end;
%mend;
%regre(a);
%regre(b); |

are dependent variable and independent variable, separately.

发帖数: 2007 | 3 Thanks. Your approach would work. But my real problem is to
work on two proc's based a macro variable value. To make it
work, I have to make the above example work with the if else.

said.

I have made my original code compiled. But it seems that,
from MPRINT, the part in %if ... %do; ... %end; is ignored.
It is really weird.
