[Limdep Nlogit List] Ordered probit model with sample selection for panel data?

[Wells, Aaron]

Is anyone aware of whether Limdep can estimate an ordered probit model
with sample selection for (unbalanced) panel data?  I have set up the
following model, but the selection model is not estimated.

Thank you,

Aaron

PROBIT; Lhs = Ace_Dumm; Rhs = one, age, female; Pds = pds; Hold$
ORDERED; Lhs=ACE_CAT2; Rhs=x2; Pds=PDS; Selection; Maxit=1000$
