Dear all, I'm trying to estimate beta regression with the betareg package and VGAM package
With the betareg package (Cribari-Neto and Zeilis) I use this code betareg(formula, data) In my mind it possible with VGAM function vglm as vglm(formula,betaff, data) But betaff have two shapes and all coefficients are doubled in the second estimation. Is it possible to obtain the same estimation with the two packages ?
