RE: st: RE: Frontier,stata 8 & stata 9
Regardless of significance or non-significance,
forcing any model through the origin -- if that
is what you are implying -- is usually
a good idea if and only if there are substantive
(meaning scientific) grounds for thinking that
that is the correct functional form. There is a short
but intensely intelligent discussion of the point
in McCullagh and Nelder's 1989 book. (Reference in
[R] glm.)
