R Package for Ecological Inference in 2x2 Tables
Description
eco is a publicly available R package that implements the Bayesian
and likelihood methods proposed in Imai, Lu, and Strauss (2006) for
ecological inference in 2x2 tables as well as the method of
bounds introduced by Duncan and Davis (1953). The package fits both
parametric and nonparametric models using either the
Expectation-Maximization algorithms (for likelihood models) or the
Markov chain Monte Carlo algorithms (for Bayesian models). For all
models, the individual-level data can be incorporated into their
estimation whenever such data are available. The package also
provides a functionality which allows one to quantify the effect of
data aggregation on parameter estimation and hypothesis testing
under the parametric model.
