The goal of healthcare.antitrust is to provide a set of tools commonly used in the antitrust analysis of healthcare markets. The main functions of the package can be used to implement the semiparametric estimation technique described in Raval, Rosenbaum, and Tenn (2017) “A Semiparametric Discrete Choice Model: An Application to Hospital Mergers.”

Users of the statistical software Stata can use the Stata module “divratio” available from the SSC repository to implement many of these same tools.
