... mortality by comparing mean LDL values across groups defined by vital status at 5 years using a t test that allows for the possibility of unequal variances across groups. How do the results of this analysis differ from those in problem 1? (Again, we do not need a formal report of the inference.) Usi ...

... During the last few years, using matching estimators in evaluation studies of treatment effects has skyrocketed. In particular, two factors have favored the diffusion of these methods in empirical works. First, the findings by Dehejia and Wahba (1999, 2002) about the promising performance of propens ...
