Paul and Greg already gave you good answers to this [as usual!].  But
I have a question.  Why would you want to do this?  I'm serious.  The
statistical ramifications are fairly well understood.  So unless you're
doing
this as a demonstration, I don't see why you would need to go through
this
exercise in the first place.
