In this article, some simple methods for testing and estimating the parameters of some discrete distributions are proposed. For hypothesis testing, a new test is obtained by combining the usual exact test and an alternative exact test. The exact properties of the usual exact test, the alternative exact test and the combined test are evaluated numerically for the binomial and Poisson distributio...

A case-control study in Rio de Janeiro in 1994 included 552 patients with a positive culture for Mycobacterium tuberculosis and reported a 1.8% resistance rate to rifampicin and isoniazid. Prior treatment for tuberculosis (the exposure factor) was associated with resistance. The binomial proportion was used to test the hypothesis of no dependence between the observed associations based on prior...
The beta-binomial distribution is resulted when the probability of success per trial in the binomial distribution varies in successive trials and the mixing distribution is from the beta family. For experiments with binary outcomes, often it may happen that observations exhibit some extra binomial variation and occur in clusters. In such experiments the beta-binomial distribution can generally ...
Recent scholarship shows that social capital has a large influence on political behavior. Social capital’s definition includes trust, norms of reciprocity, and social networks. Most studies, however, ignore the networking component. Here, we test the influence of social networks on political participation using new Japanese survey data. We separately test the effects of involvement in formally ...
