st: "outreg" for d-stats, comparison of means tests, etc.

[Kit Baum <baum@bc.edu>]

As a postscript to my earlier posting, and complementary to Nick's 
posting:

outtable can produce an output file from any Stata matrix. By looping 
over the rows and columns, you can create whatever (numeric) contents 
you like in that matrix. Many users may think that matrices are 
something best avoided since that disastrous course in linear algebra, 
but Stata matrices can be very usefully employed to organize results 
and display them. I just proofread the galleys of a forthcoming paper 
in which we used matrices to display the counts of various logical 
conditions over a large set of estimates: e.g. how many lambda-hats 
were signif pos, how many signif neg, etc, No vector spaces here!

So outtable could be used after statsby, but outtable could also be 
used with a matrix declared and filled by any other sequence of Stata 
commands. All you have to do is define counters that cycle over rows 
and columns to produce the matrix (==table) that you like.

It may be noted that outtable produces LaTeX output, not tab-delimited 
output; an enterprising user could no doubt modify a copy of outtable 
to produce the latter if they were inclined. I do not use MS Word for 
serious work, so tab delimited files are not a priority.

Thanks
Kit
