A Bayesian Version of Rasch's Multiplicative Poisson Model for the Number of Errors of an Achievement Test.
Peer reviewed Peer reviewed
Jansen, Margo G. H. – Journal of Educational Statistics, 1986
In this paper a Bayesian procedure is developed for the simultaneous estimation of the reading ability and difficulty parameters which are assumed to be factors in reading errors by the multiplicative Poisson Model. According to several criteria, the Bayesian estimates are better than comparable maximum likelihood estimates. (Author/JAZ)
