Bayesian beta negative binomial distribution
WebBeta-Negative Binomial Process and Poisson Factor Analysis nomial distribution. The BNB process is formulated in a beta-gamma-gamma-Poisson hierarchical structure, with which we construct an in nite PFA model for count matrix factorization. In probability theory, a beta negative binomial distribution is the probability distribution of a discrete random variable $${\displaystyle X}$$ equal to the number of failures needed to get $${\displaystyle r}$$ successes in a sequence of independent Bernoulli trials. The probability $${\displaystyle p}$$ of … See more Denoting $${\displaystyle f_{X p}(k q),f_{p}(q \alpha ,\beta )}$$ the densities of the negative binomial and beta distributions respectively, we obtain the PMF $${\displaystyle f(k \alpha ,\beta ,r)}$$ of the BNB … See more • Interactive graphic: Univariate Distribution Relationships See more The beta geometric distribution is an important special case of the beta negative binomial distribution occurring for $${\displaystyle r=1}$$.

WebApr 23, 2024 · In Bayesian analysis, named for the famous Thomas Bayes, we model the deterministic, but unknown parameter θ with a random variable Θ that has a specified distribution on the parameter space T. Depending on the nature of the parameter space, this distribution may also be either discrete or continuous. http://proceedings.mlr.press/v22/zhou12c/zhou12c.pdf
