A Berry-Esseen theorem for Pitman's $\alpha$-diversity
, 2020 This paper is concerned with the study of the random variable $K_n$ denoting the number of distinct elements in a random sample $(X_1, \dots, X_n)$ of exchangeable random variables driven by the two parameter Poisson-Dirichlet distribution, $PD(\alpha ...

Dependence on a collection of Poisson random variables [PDF]
Statistical Methods & Applications, 2021 We propose two novel ways of introducing dependence among Poisson counts through the use of latent variables in a three levels hierarchical model. Marginal distributions of the random variables of interest are Poisson with strict stationarity as special case.

A geoadditive Bayesian latent variable model for Poisson indicators [PDF]
, 2006 We introduce a new latent variable model with count variable indicators, where usual linear parametric effects of covariates, nonparametric effects of continuous covariates and spatial effects on the continuous latent variables are modelled through a ...

Some estimates of the normal approximation for mixture of Poisson and gamma random variables
Lietuvos Matematikos Rinkinys, 2010 In the paper, we present the upper bound of Lp norms ∆p of the order (a1 + a2)/(DZ)-1/2 for all 1 0, and the random variable Y by the standard gamma distribution Γ (α, 0, 1) with the parameter α > 0.

Compound Poisson Approximation for Dissociated Random Variables via Stein's Method [PDF]
Combinatorics, Probability and Computing, 1999 In the present paper we consider compound Poisson approximation by Stein's method for dissociated random variables. We present some applications to problems in system reliability. In particular, our examples have the structure of an incomplete U-statistics.

A refinement of normal approximation to Poisson binomial
International Journal of Mathematics and Mathematical Sciences, 2005 Let X1,X2,…,Xn be independent Bernoulli random variables with P(Xj=1)=1−P(Xj=0)=pj and let Sn:=X1+X2+⋯+Xn. Sn is called a Poisson binomial random variable and it is well known that the distribution of a Poisson binomial random variable can be ...

Weighted Naive Bayes Text Classification Algorithm Based on Poisson Distribution [PDF]
Jisuanji gongcheng, 2020 Naive Bayes(NB) algorithm is simple and efficient when applied to text classification,but it has a bottleneck in accuracy due to the intrinsic assumption that attribute independence and attribute importance are consistent.To solve this problem,this paper

The Length-Biased Versus Random Sampling for the Binomial and Poisson Events [PDF]
, 2013 The equivalence between the length-biased and the random sampling on a non-negative, discrete random variable is established.
