Hello All,

I received the following message and I think it is regarding start values or the method.

semsem = mlogit.optim ( LL=LL*Prob[i,1] , start = c(1,1,1), method = c("bfgs"), iterlim = 2000, tol = 1E-05, ftol = 1e-08, steptol = 1e-10, print.level = 2)
+ }

Error in as.name(f[[2]]) : 
  'pairlist' object cannot be coerced to type ‘symbol'

Do you have an idea how to fix this?

Thanks in advance
