[Limdep Nlogit List] Ordered Probit Model with Selection

[james benson]

Hi,
Will it be possible for me to estimate an ordered probit outcome model 
while accounting for selection using an ordered probit selection model?  
If so, is there any advantage to estimating this type of model in 
NLOGIT, as compared to LIMDEP.  For my dissertation research, I need to 
model students' selection into three ordered states (no college, 2-year 
college, and 4-year college) and their attainment outcome which also 
takes on three states (no degree, 2-year degree, and 4-year degree).  
LIMDEP looks like the only software around that can estimate such a 
model, but I need to confirm this before I can get approval to purchase it.
