Here are the same two years of outcome data, but now each hospital/year combination has an additional number associated with it: the VA's case-mix adjustment factor that, for each hospital in each year, is supposed to be a predictor of the fraction of returns. This plays the role of a covariate in models for the outcomes. The two years are given here separately, 1992 and 1993
Here is a much larger exchange rate data set. Daily spot prices and corresponding returns for several years.
