Title: Simple interface to the estimation and plotting of IRT models
Description: Provides a simple common interface to the estimation of item parameters
in IRT models for binary responses with three different programs (ICL,
BILOG-MG, and ltm, and a variety of functions useful with IRT models.

Title: A Collection of Functions Related to Item Response Theory (IRT)
Description: A collection of functions useful in learning and practicing IRT,
which can be combined into larger programs. Provides basic CTT analysis,
a simple common interface to the estimation of item
(ICL, BILOG-MG, and ltm), ability estimation (MLE, BME, EAP, WLE, plausible
values), item and person fit statistics, scaling methods (MM, MS, Stocking-Lord,
and the complete Hebaera method), and a rich array of parametric and
non-parametric (kernel) plots. Estimates and plots Haberman's interaction model
when all items are dichotomously scored.
