Description: eco is a publicly available R package that implements the
        Bayesian and likelihood methods proposed in Imai, Lu, and
        Strauss (Forthcoming) for ecological inference in $2 \times 2$
        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 directly incorporated into the
        estimation whenever such data are available. Along with
        in-sample and out-of-sample predictions, 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 likelihood models.
