Note that it produces not only a Gini estimate, but also an estimate of its standard error (using linearisation methods). If Ilya does not require an estimate of the standard error -- she does not say -- then there are large number of programs that will yield it, even for weighted data (see recent Statalist posts). They include -ineqdeco- (or -ineqdec0-) by me, and -inequal7- by Philippe Van Kerm. (My recollection is that -inequal- has problems; they motivated Philippe's -inequal7-). Be aware that -ineqerr-, from STB-51 and a version 5 program, (not authored by me) uses bootstrap methods to derive standard errors. However, if you have weighted data, plain vanilla bootstrap methods (as in -ineqerr-) do not necessarily produce estimates with all the desired properties. Check out Stas Kolenikov's Statalist posts on this topic, and his recent presentation at NASUG. Stephen ------------------------------------------------------------- Professor Stephen P.
