I want to write a do-file that uses loops to refer to some global macros.
Global macros define different variables that I want to use in different
regressions. However, when I run program I receive an error. Example of
the do-file is goes like this:
version 7
global cov1="var3"
global cov2="var3 var4"
global cov3="var3 var4 var5"
local i=1
while `i'<=3 {
logistic y var1 var2 $cov`i'
local i=`i'+1
}
After I run this do file it gives an error:
1 invalid name
r(198);
Does this mean that I can not use loops that refer to macros? What should I
change for this to run? Any advise would be appreciated. Option to write
explicitly each regression does sound quite attractive.
Thanks,
