wallace

<p>This data set contains, on a county level, the proportion of county
residents who are Black and the proportion of presidential votes cast for
Wallace.  Demographic data is based on the 1960 census. Presidential returns
are from ICPSR study 13.  County data from 10 southern states (Alabama,
Arkansas, Georgia, Florida, Louisiana, Mississippi, North Carolina, South
Carolina, Tennessee, Texas) are included. (Virginia is excluded due to the
difficulty of matching counties between the datasets.)  This data is
analyzed in Wallace and Segal (1973).</p>

datasets

Implements the Bayesian and likelihood methods proposed
in Imai, Lu, and Strauss (2008 <DOI: 10.1093/pan/mpm017>) and
(2011 <DOI:10.18637/jss.v042.i05>) for ecological inference in 2
by 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.
