Dear all,

I'm trying to get some LaTeX code into an estout-output. I estimate different models for some different units, so I wanted to group these models by suboption "mgroups":

...mgroups("country1" "country2" , pattern(1 0 0 1 0 0) span prefix(multicolumn{@span}{c}{) suffix(}))...

stata reports: "option prefix() not allowed...Any suggestions?

Thanks,
Johannes Geyer
