How do you go about creating the weights for each pair, and are you suggesting that we can just incorporate a weight statement in the model as opposed to the strata statement? And Dr. Therneau, let's say I have 140 cases matched with replacement to 2 controls. Is my id variable the number of cases?

  The above has an incorrect assumption that I notice ALL survival questions on the list 
-- which was false in this case.  Could you clue me in as to the original question and 
discussion -- assuming that you want "Dr Therneau" to respond intelligently :-)
