Hi, Steve, I am a old school and not a big fan of getting the "P-value" from SAS and then looking for a way to explain it. So what I suggest is to learn stat101 first before using SAS to calculate the lovely "P-value". This will take you a long way and benefit you more.

Wensui, Thanks; I see it now; it means that the error terms don't have a mean of = 0 and and a normal distribution if you truncate. Given that credit companies massively up their interest rates and fees = when they anticipate that someone will be declaring bankruptcy, it does = seem that the assumption that people only have to pay a maximum of what = they owe is a bit suspect anyway :-).
