I have a specification of latent class multinomial model (below)

lclogit; choices=air, car, bus, train, none
               ; lhs=choicem
               ; model: U(air, car, bus, train) = <asca, ascc, 0, asct>
                              + <da, dc, db, dt> * duration + pc * price
                              / U(none) = anone
               ; show model
               ; pds=6; pts=2
               ; wtp=da/pc, dc/pc, db/pc, dt/pc$

This works fine, parameters are significant and the matrix wtpi is created with four columns and nearly 300 rows (the individuals). But filled only with zero. What is wrong?
