When the poster wrote to me off-list a week ago, I replied:
"Please *do* write to the R-sig-geo list rather than to me directly -
others can answer your question as well, perhaps better, and in a more
timely way than I can. In addition, threads in the list can be searched in
the archives, so others can avoid the same problem later.
Please when you post indicate the published paper defining the LL of this
It is instructive to run:
logLik(tsls(Q ~ P + D, ~ D + F + A, data=Kmenta))
which explains why I asked for a publication providing something which
doesn't spring naturally from the estimation method.
