I think more readable code would be something like
gen w = .
replace w = 1 if D>=L & D>=U & !mi(D)
replace w = 0 if L>=D & L>=U & !mi(L)
replace w = 0.5 if U>=L & U>=D & !mi(U)
You should think carefully about inclusion / non-inclusion (>= vs. >) in
the above. The argmax is not unique when say D==L, and your code might
have problems with it just as mine does.
If w is indeed an integer (as you said in the introduction, but did
contrary to that in the code), you would store it more efficiently with
-byte-. Even the way it is defined, w can be stored as -float- without any
loss of precision since all of 0, 1 and 1/2 are stored accurately in the
binary presentation.
