We introduce a combinatorial stochastic process known as thennegative binomial processn(n${rm NBP}$n) as an infinite-dimensional prior appropriate for such problems. We show that then${rm NBP}$nis conjugate to the beta process, and we characterize the posterior distribution under the beta-...
The marginal distribution of the counts is then Beta-Binomial. Bradlow, Hardie, and Fader (2002, p. 189) make use of polynomial expansions to simplify Bayesian computations with Negative-Binomial distributed data. This article exploits similar expansions to facilitate Bayesian inference with data ...
Poisson distribution (generally the negative-binomial distribution [5-7]), although the beta-binomial distribution [8] has also been used. These methods offer relatively robust and sensitive detection of differential expression either through pairwise comparisons [6,7] or a model-based approach [5]...
Binary Regression Using an Extended Beta-Binomial Distribution, with Discussion of Correlation Induced by Covariate Measurement Errors The beta-binomial distribution is extended to allow negative correlations among binary variates within an experimental unit. Regression models are proposed... RL Prentice -...
