Hi,

I am trying to ascertain whether I can estimate a mixed multinomial logit model using gllamm6 using panel data and want to restrict the parameters to be equal across equations while allowing for 3 random parameters. I think the syntax below is correct but am not sure and cannot see where it is possible to change the distribution of the random parameters to be other than normal? Could anyone offer any help?

Outcome here is the outcome variable, regressors are our x variables, pid is the individual identifier:

gllamm6 <outcome> <regressors>, i(pid) nrf(3)-[we have three random parameters] eqs(the variables that have random coefficients) family(binomial) link(mlogit) expanded(response options o)


Any help would be very much appreciated.
Matt
