asymmetric: A package for analyzing asymmetric hypotheses.


asymmetric is an R package that enables researchers to estimate data boundaries when studying asymmetric hypotheses. The package includes various techniques for estimating boundaries such as stochastic frontier analysis, quantile regression, and kernel estimation; it also includes a method for testing whether data are asymmetric (Area Outside the Curve).  In addition, a function for calculating confidence intervals via a resampling technique is provided. The package implements methods described in Rosenberg, Knuppe, and Braumoeller (2017) "Unifying the Study of Asymmetric Hypotheses." Political Analysis, Forthcoming.
