Central limit theorems for generalized Pólya urn models
Central limit theorems for generalized Pólya urn models
In this paper we obtain central limit theorems for generalized Pólya urn models with L ≥ 2 colors where one out of K different replacements (actions) is applied randomly at each step. Each possible action constitutes a row of the replacement matrix, which can be nonsquare and random. The actions …
