Duijn, Marijtje A. J. van; Jansen, Margo G. H.
Journal of Educational and Behavioral Statistics, v20 n3 p241-58 Fall 1995
The Rasch Poisson Counts Model, a unidimensional latent trait model for tests that postulates that intensity parameters are products of test difficulty and subject ability parameters, is expanded into the Dirichlet-Gamma-Poisson model that takes into account variation between subjects and interaction between subjects and tests.
