RT journal article T1 Contagious statistical distributions: k-connections and applications in infectious disease environments. A1 García García, Víctoriano José A1 Martel-Escobar, María A1 Vázquez-Polo, F.J. A2 Estadística e Investigación Operativa AB Contagious statistical distributions are a valuable resource for managing contagion bymeans of k–connected chains of distributions. Binomial, hypergeometric, Po´ lya, uniform distributionswith the same values for all parameters except sample size n are known to bestrongly associated. This paper describes how the relationship can be obtained via factorialmoments, simplifying the process by including novel elements. We describe the propertiesof these distributions and provide examples of their real–world application, and then definea chain of k–connected distributions, which generalises the relationship among samples ofany size for a given population and the Po´lya urn model.
