Re: st: control a variable in stata

[Nora Reich <nhmreich@googlemail.com>]

As far as I know, -poisson- is for skewed distributions, and salary
distribution in general often fulfills this requirement, but salary of
NBA players might show a different distribution. The distribution can
be checked, e.g. with the command

-histogram salary-

(for more information type -help histogram-).

Andy, I would compare the assumptions and requirements of different
estimation strategies (OLS, poisson) and find out which fits better
with the data.

I would also check which estimations strategies are used by similar
papers, and why.

Apart from -poisson- and -regress-, I cannot think of any at the
moment that have to be considered for your salary-estimations.
However, if there was something like a "minimum wage" for NBA players,
i.e. salary is censored,  -tobit- would be an alternative.

Best regards
Nora
