Estimation of Causal Effects
Jonsson Funk, et al. have developed a SAS® macro for doubly robust estimation of the effect of a dichotomous treatment (or exposure) on a continuous or dichotomous outcome with bootstrapped standard errors. Base SAS v8 or later is required.

Doubly Robust Estimation of Treatment Effects
Jonsson Funk M. 23rd ICPE Meeting, August 19-22, 2007, Quebec City, Canada.
Funding for the development of the macro was initially provided by the Agency for Healthcare Research & Quality (AHRQ) through a supplemental grant to the UNC Centers for Education & Research on Therapeutics (CERTs) (3U18HS010397-07S1). Ongoing work is supported by AHRQ through a career development award to Dr Jonsson Funk (K02HS017950).
We would like to acknowledge the valuable contributions of Harry Guess, MD, PhD (deceased) to this project. We would also like to thank our colleagues at the Duke Clinical Research Institute and students in the Epidemiology Department at the University of North Carolina who provided feedback on early versions of the macro.
