Hello,
I am using the VGAM library to perform a multinomial logistic regression

Hello,
I am using the VGAM library to perform a multinomial logistic regression
with 3 outcome categories and a binary independant factor.
How can I constraint the 2 beta parameters to be equal. I intend to do that
in order to obtain a Log-Likelihood to test against the model with 2
different beta parameters.

This is part of my script :

library(VGAM)
Factor <- c(0,1)
DataSample <- cbind(c(88,75), c(249,88), c(405,95))
Mlogit.fit <- vglm(DataSample ~ Factor, family = multinomial())


Thank you.
