Dear all,
I am trying to estimate an mlm with 8 alternatives, but I received the
following error message:
Error in `colnames<-`(`*tmp*`, value = "disto.disto") :
attempt to set colnames on object with less than two dimensions
My data look like this:
> head(dtb)
votechoice disto.CVP disto.FDP disto.GPS disto.LPS disto.PBD disto.SP
disto.SVP disto.VL risk

When I estimate a simple logit model it is working:
rpl2 <- mlogit(votechoice ~ disto | risk,data=newdtb, shape =
'wide',varying=2:9, correlation=T,
halton = NA,R = 10, tol = 10, print.level = 0);summary(rpl2)
but when I am trying to estimate an mlm, I get the following:
> rpl2 <- mlogit(votechoice ~ disto | risk,data=newdtb, shape =
> 'wide',varying=2:9,correlation=T,
+ rpar=c(disto='l'),halton = NA,R = 10, tol = 10, print.level = 2)
Error in `colnames<-`(`*tmp*`, value = "disto.disto") :
attempt to set colnames on object with less than two dimensions
I would be grateful for any help, thanks for reading this post.
