Hiroshi. You cannot have missing values in the setup for the NLOGIT model.
The program cannot figure out what to do with the data.  For any observations
you expect to be using, CSET must give the appropriate count.  Likewsie, if you
code the 4th alternative as -999, the observation will be discarded.  Use 0.
