Re: st: how to get dfbetas in StataIntercooler with more than 800 observations?

[Enzo Coviello <enzo.coviello@alice.it>]

Dear Jose Maria,

I believe that what you are looking for is -stpm- 
a command written by prof Thomas Lumley no more available as far as I know.

Privately I send a copy of this version 6 command.
There two problems:
1) I haven't the help file. So you should deduce 
the use by the syntax but it should not tto complicate.
2) The present -stset- statement should work, but I am not sure about that.

Besta wishes.

Enzo
