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 $2 \times 2$ 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.
