Ecological inference (EI) takes contingency tables as the unit of analysis. These tables are described by row and column totals (or proportions); the goal of inference is to determine the marginal intra-table relationship between the rows and columns. While some existing R packages (MCMCpack by Andrew Martin and Kevin Quinn and eco by Kosuke Imai and Ying Lu, for example) offer functions that analyze 2 x 2 models, we implement more general methods that can take more than two rows or columns. Our package includes:
- Extreme case analysis, or the method of bounds, suggested by Duncan and Davis (1953)
- Ecological regression described in Goodman (1953) using both frequentist point estimates and a Bayesian estimator that produces correct standard errors.
- R x C model described in Rosen et al. (2001) using a Bayesian Markov-chain Monte Carlo algorithm
