Description:
Implements the Bayesian and likelihood methods proposedin Imai Lu and Strauss 2008 DOI 10.1093panmpm017 and2011 DOI10.18637jss.v042.i05 for ecological inference in 2by 2 tables as well as the method of bounds introduced by Duncan andDavis 1953. The package fits both parametric and nonparametricmodels using either the Expectation-Maximization algorithms forlikelihood models or the Markov chain Monte Carlo algorithms forBayesian models. For all models the individual-level data can bedirectly incorporated into the estimation whenever such data are available.Along with in-sample and out-of-sample predictions the package alsoprovides a functionality which allows one to quantify the effect of dataaggregation on parameter estimation and hypothesis testing under theparametric likelihood models.
