Before revision:  We compare MNP, MNR and Gen-MNR in a simulation study and a case study on transport mode choice behaviour . We find that both MNR and Gen-MNR deliver significantly better in-sample fit and out-of-sample predictive accuracy than MNP. Gen-MNR outperforms MNR due to its more flexible kernel error distribution.
