The Beta‐Binomial Model for Host Specificity among Organisms in Trophic Interactions

Biometrics, 2000
Summary. In this paper, we present a new stochastic model where the host specificity among organisms in trophic interactions in a community, say parasite‐host interactions, is estimated by a beta‐binomial model. The expected proportion of the host species in a community that a given parasite species is utilizing is modeled as a realization from an ...

A note on bayesian estimation and prediction for the beta-binomial model

Journal of Statistical Computation and Simulation, 1999
The beta-binomial model which is generated by a simple mixture model has been widely applied in the social, physical, and health sciences. Lee and Sabavala (1987) proposed a Bayesian approach with a conjugate-type beta family of priors for suitably transformed parameters in the beta-binomial, and demonstrated the simulations for a special case of two ...

THE APPLICABILITY OF THE BETA BINOMIAL MODEL FOR CRITERION REFERENCED TESTING

Journal of Educational Measurement, 1980
In recent years, the solutions to various problems in criterion referenced testing have been studied within the framework of the beta binomial test model. For example, using this model, investigators have offered solutions to the following problems: the determination of test length, (Novick & Lewis, 1974), cutoff scores (Huynh, 1976b, 1977 ...

Bayesian residual analysis for beta-binomial regression models

AIP Conference Proceedings, 2012
The beta-binomial regression model is an alternative model to the sum of any sequence of equicorrelated binary variables with common probability of success p. In this work a Bayesian perspective of this model is presented considering different link functions and different correlation structures.

Optimal designs for beta-binomial logistic regression models

Journal of Applied Statistics, 2003
Optimal designs for a logistic regression model with over-dispersion introduced by a beta-binomial distribution are characterized. Designs are defined by a set of design points and design weights as usual but, in addition, the experimenter must also make a choice of a sub-sampling design specifying the distribution of observations on sample sizes.
