Thank you Scott. This is very helpful. One more question if you can
answer please. You can run regression by group (e.g. regression by
each industry group). Can one also do the above analysis by group. I
tried to use bysort function but didn't work. Is there a way to do run
above command by group?

Again, thanks everyone for replying.
