Re: st: table formatting in stata

[Sergiy Radyakin <serjradyakin@gmail.com>]

Hi, I really want to help, but I am afraid I can't understand the
problem. Partially because it seems to me there is a part of the email
missing. Also, in Stata 'casewise' means observation as a whole, not
'individual variable' which I think you are confusing here. See here
for examples:
http://books.google.com/books?id=zCym0GtuRE4C&lpg=PA25&ots=i2igqfWYtu&pg=PA25#v=onepage&q&f=false

I have reproduced the output of the all 51s, and have modified it to
show 51 where appropriate in your example.

You can reinstall the package.

Best, Sergiy
