Even if somebody knew exactly what "Wooldridge" said, (s)he might want to consider having a look at it again before posting anything. Trying to figure out where exactly (journal?, book?, page?) he said what may become a burden for this group of people. On the other hand, people who do not know (exactly) what "Wooldridge" said might ditch this posting right away instead of trying to figure out when and where he could have said that. In any case, your chances of getting a reply will decrease without proper referencing. Please see http://www.stata.com/support/faqs/resources/statalist-faq/ especially 3.4.
