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
