Hi
I am using a linear regression to evaluate the impact of a treatment effect after matching (psmatch) with replacement and K:1 (k>1). What is the easier way to obtain robust standard errors which account for the fact that control observations are being used multiple times? Sample>10k.
Thank you

There is PROC ROBUSTREG .
But I am doubt that if it was what you are looking for.

It would be interesting to know if it has been used to estimate the treatment effect after matching with replacement and k:1.

That is not really .
It don't care whether the data is "matching with replacement and k:1." or not,
It is just consider the high leverage point(for X variables) and outliers point(for Y variable),
and get rid of these point to fit a regression model (a.k.a robust mean or std ).
Anyway, @StatDave @Rick_SAS maybe could give you the answer.

I do not understand the question, so I cannot add to this discussion.

The question is how to obtain robust standard errors when using a linear regression to estimate the impact of the treatment effect after matching with replacement and k=n, distance=pscore
