Fixing a parameter in mlogit by MAXLIK [ Reply ] By: Md Ridwan Bin Alam on 2023-06-01 07:11

Hello, If I run the code below- library(mlogit) data("Fishing", package = "mlogit") Fish <- mlogit.data(Fishing, varying = c(2:9), shape = "wide", choice = "mode") m<- mlogit(mode ~ 0| income, data = Fish) summary(m) i am getting the output attached as image. My query is, In the above code, if I want to fix the coefficient of income:charter as zero (making it zero will affect the other coeffcients) as it is not statistically significant, how can I use the maxlik package to obtain the wanted output? I have read the maxlik package manual and did not understand the fixing constraint part. Thank you.
