Maarten--
While -intreg- does seem tailor-made in some ways for this problem of
testing whether e.g. E(Y|X=A)>E(Y|X=B) when Y is discretized as Y*
(measured in large intervals), by simply typing e.g.
    intreg ystar groupA
the assumption in -intreg- is that e (or Y-bX) is N(0,s) which seems
unlikely to hold true for incomes measured in dollars.
