I am guessing that this is one of the predicted values possible 
with -tobit- and are thus possible to obtain via -mfx-, but I 
would need to look at the paper documentation of -tobit- to say 
more, and I am away from home right now. Maybe somebody else 
can help.

Remember that this is an interdisciplinary list, so any 
name-year references that are completely obvious within your 
discipline are completely meaningless here. So please give 
complete references.
