[R] Cox regression model for matched data with replacement

[John Pura]

I am curious about this problem as well. 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?

Thanks,
John
