TM <- mlogit.data(TravelMode, choice = "choice", shape = "long",
alt.levels = c("air", "train", "bus", "car"))
myweight = rep(floor(1000*runif(nrow(TravelMode)/4)), each = 4)
summary(mlogit(choice ~ wait + vcost + travel + gcost, data=TM))
summary(mlogit(choice ~ wait + vcost + travel + gcost, weights=income, data=TM))
summary(mlogit(choice ~ wait + vcost + travel + gcost,
weights=myweight, data=TM))
Each gives the same result. Am I specifying "weights" incorrectly?
Is there a better way to do...
