Re: st: "by" option can't be command with "do" command

[Andrew Dyck <tempmail@andrewdyck.com>]

Hi Tuki,

Presumably, you have written a program in the do-file you are trying
to call with the -by- command. Assuming that you have written a
program of the form:

capture drop program gridSearch
program define gridSearch
    ....stuff....
end

and this program is defined in a do-file name 'gridSearch.do'

You should be able to accomplish your task by including the program in
your main do-file document like so:

include "gridSearch.do"

And then, call the program in your main document with the -by- command.

bysort hs : gridSearch

Now, the last assumption here is that you have defined your gridSearch
program to be -byable-. There is a good amount of information online
about writing Stata programs to cover this part. I'd take care to test
these programs quite a bit though to make sure it's doing what you
think it's doing.

Good luck!

Andrew
