[Limdep Nlogit List] Problem with NLSUR

[Rao, James]

Hi, 

In estimating the a non linear systems of equations am using the NLSUR
command that corresponds to "nonlinear IV systems of equations (NL3SLS)". In
the table of results shown below, I wonder whether or not its right that the
"Number of parameters is shown to be = 0"

Is it also right that my information criteria are all the same?

| Nonlinear minimization over  3 equations.   |
