Comparative Studies:
Matching, Adjustment, and Propensity Scores
May 27, 2009
Edward Rothman (CSCAR)
Ben Hansen (Dept. of Statistics / ISR)
In an observational study, a researcher attempts to understand effects of an intervention upon people, without controlling which of them receive the intervention. Common in medical and social research, observational studies generally compare groups exposed to two or more contrasting conditions, restricting the focus of their comparisons not with experimental control but by statistical adjustment, and by artful choice of observations. In general, case-control studies, cohort studies and cross-sectional comparisons are all observational studies.
Designs and analyses of observational studies vary greatly, but some common threads join the most successful of them. The workshop discusses a number of these in general terms and gives a detailed overview of matching and related adjustment techniques for observational studies. This overview devotes special attention to a statistical tool called the propensity score, and to the implementation of propensity-score matching using R.
