How do I normalize the variance of error terms in multinomal logit/probit models?
Hi, I use a multinomial logit model to analyze a choice experiment with three options. I normalize the coefficient of one of the options, say option three to zero. I do this to set this option as the reference category. Hence, I am left with two options. Now I want to normalize the variance of...- Thomas.V

R mlogit: How do I interpret marginal effects using absolute or relative type?
Hi R users, I use effects() to compute the marginal effects of a mlogit model in R. effects(object, covariate = NULL, type = c("aa", "ar", "rr", "ra"), data = NULL,...) Which type ("rr", "aa", "ar", "ra") in effects() should I use when estimating the marginal effects? How do I... -

R mlogit marginal effects with alternative-invariant variables only
Hi everyone, can someone explain how to calculate the marginal effects of a multinomial logit model with alternative-invariant variables (e.g. income) only. A similar question was asked here but not answered sufficiently. The calculation works only, if I also include alternative-variant...
