Re: st: value labels in output regression model

[Roger Harbord <roger.harbord@bristol.ac.uk>]

You may like to take a look at Tony Brady's -reformat- package. Type -ssc 
describe reformat- for more info.

A simple example :

. sysuse nlsw88
(NLSW, 1988 extract)

. xi: regress wage i.race i.collgrad
i.race            _Irace_1-3          (naturally coded; _Irace_1 omitted)
i.collgrad        _Icollgrad_0-1      (naturally coded; _Icollgrad_0 omitted)

     Source |       SS       df       MS              Number of obs =    2246
-------------+------------------------------           F(  3,  2242) =   62.05

      Total |  74367.9674  2245  33.1260434           Root MSE      =  5.5342

* Baseline category

There are options to vary what is displayed and how it's formatted. I think 
it's a very useful and well-designed package. Those who like to use asterisks 
to indicate significance levels may prefer something else.
