st: Package -domin- now available in SSC

With many thanks to Kit Baum, package -domin- has been uploaded to the
SSC archive.

The -domin- command generates general dominance weights developed by
Budescu (1993; Psychological Bulletin) and are conceptually similar to
Shapley value decomposition.

The -domin- command produces additive decompositions of r2 or
pseudo-r2 (in this case, the r2o metric developed by Mike Lacy, 2006;
Sociological Methods & Research) indexes ascribing what can be
interpreted as
the "relative importance" of each variable or set of variables in the
prediction of some outcome (see Groemping, 2007; American
Statistician, for an overview).

Currently, -domin- decomposes regressions based on linear, logistic,
ordered logistic, and multinomial logistic models.

To install, write -ssc install domin-

-domin- requires Stata 10 and SSC modules -tuples- and -r2o-

Stata 11 and 10 users should note that the current version will not
run in Stata 11 or 10 as the syntax allows factor variables in the
all() option (which makes the program return an error).

An .ado file appropriate for versions 11 and 10 will be posted to my profile (see link below) this evening or tomorrow
morning (i.e., on 4/16/2013) and later uploaded to the SSC archive.
