-ineqdeco- and -ineqdec0- have been updated on SSC, thanks to Kit
Baum.

The modules compute a number of indices of inequality, and optionally
provide decompositions by population subgroups.  (-ineqdeco- requires
the variable of interest to be positive; -ineqdec0- does not enforce
this constraint, and so computes a restricted set of indices.) 

These versions correct a bug drawn attention to by Johannes Giesecke
and Austin Nichols -- subgroup decomposition calculations could fail
with error r(2000) if an if/in qualifier led to no observations in one
of more of the by groups. Austin provided code to fix the bug.
Thanks!

To get the new versions:
	ssc install ineqdeco, replace
	ssc install ineqdec0, replace
or
	adoupdate ineqdeco, ssc update
	adoupdate ineqdec0, ssc update
