No, I meant for you to
(a) show an example that anyone could run and reproduce your problem
(b) show the output you get when calling traceback() after you ran into
the error.
The lines and error messages you show now are different than the ones you
showed before, but I see you are call mlogit.optim, which I assume comes
from the mlogit pacakge. help(mlogit.optim) shows
mlogit.optim(logLik, start, method = c("bfgs", "nr", "bhhh"),
iterlim = 2000,
tol = 1E-06, ftol = 1e-08, steptol = 1e-10,
print.level = 0, constPar = NULL, ...)
Arguments:
logLik: the likelihood function to be maximized,
It looks like your LL is a numeric vector and mlogit.optim expects a
function,
so the original error message may come from there.
By the way, you should stop at the first error message and straighten
things out
before proceeding. Otherwise all is likely to be garbage.
