WebApr 26, 2015 · The gap is due to two factors: (1) The multinomial() family in VGAM chooses the reference to be the last level of the response factor by default while multinom() in nnet always uses the first level as the reference. (2) The species categories in the iris data can be separated linearly, thus leading to very large coefficients and huge standard errors.
