    I want to check if my data has scale heterogeneity via a generalized multinomial logit model (G-MNL) in the discrete choice experiment model as described by Gu, Y., Hole, A. R., & Knox, S. (2013). My code is
    HTML Code:
    gmnl Y   asc fish_d2 fish_d3 vet_d2 vet_d3 alc_d2 alc_d3 smk_d2 smk_d3 pqt_d2 pqt_d3, group(ncs) id (ID) n
    > rep(500) scale(scale)
