If you look at the decomposition-of-inequality-change expressions provided on page
896 of Mookherjee and Shorrocks (1982), you'll see no use of "subgroup sum of
weights" (that was provided in -ineqdeco- as a saved result for completeness's
sake). Perhaps you're thinking of the subgroup population share terms (v_k)?
Whatever, I think you should be able to calculate all the elements of their
equation from what is returned after -ineqdeco- (or -ineqdec0-)

Subject: Re: st: new ineqdeco - capturing results for dynamic decomposition
Thanks very much for this very helpful advice, I can
now capture the results perfectly.
However, I'm still not getting the right end results
and I think it may be because I'm not weighting the
subgroups properly. Returning to my question below,
could I ask whether the "subgroup sum of weights" is
meant to be incorporated into the decomposition?
Again, many thanks.
