Confidence regions for two proportions from independent negative binomial distributions

The negative binomial distribution offers an alternative view to the binomial distribution for modeling count data. This alternative view is particularly useful when the probability of success is very small, because, unlike the fixed sampling scheme of the binomial distribution, the inverse sampling approach allows one to collect enough data in order to adequately estimate the proportion of success. However, despite work that has been done on the joint estimation of two binomial proportions from independent samples, there is little, if any, similar work for negative binomial proportions. In this paper, we construct and investigate three confidence regions for two negative binomial proportions based on three statistics: the Wald (W), score (S) and likelihood ratio (LR) statistics. For large-to-moderate sample sizes, this paper finds that all three regions have good coverage properties, with comparable average areas for large sample sizes but with the S method producing the smaller regions for moderate sample sizes. In the small sample case, the LR method has good coverage properties, but often at the expense of comparatively larger areas. Finally, we apply these three regions to some real data for the joint estimation of liver damage rates in patients taking one of two drugs.     

A comparison of estimators of the degree of insect control

The current estimator of the degree of insect control by an insecticide in a field experiment laid out in randomized blocks is equal to one minus the cross-product ratio of a two way table of total insect counts over blocks. Since much work has been done on estimation of the common odds ratio of a number of strata in medical studies, a series of Monte Carlo studies was performed to investigate the possible use of these estimators and their standard errors in estimating the common degree of inject control of a number of blocks. Maximum likelihood, Mantel-Haenszel, and empirical logit estimators were evaluated and compared with back-transformed means over blocks, of cross-product ratios on the arithmetic, logarithmic, and arcsine scales. Maximum likelihood and Mantel-Haenszel estimators had the smallest mean squared errors, but their standard error estimates were only appropriate when sampling distributions were approximately Poisson and there was little heterogeneity among plots within blocks in the natural rates of population change.     

Typology of Gay Consumers’ Interaction Styles on Complaining Propensity

The purpose of this study is to develop a typology of gay male consumers based on self-concept variables related to social interactions. Openness about sexual orientation, collective self-esteem, stigma-consciousness, and negative evaluation were used to identify clusters of gay male consumers. An initial test sample (n = 125) suggested a three-cluster solution, and a validation sample (n = 247) established reproducibility of the proposed typology. Three clusters with distinct interaction styles emerged: “confident gay,” “diffident gay,” and “guarded gay.” Additionally, the usefulness of the typology is demonstrated by comparing the clusters on the basis of complaining propensity. Typologies of each cluster and implications for research and practice are discussed.

On the differences of two generalized negative binomial variates

The generalized negative binomial (GNB) distribution was defined by Jain and Consul (SIAM J. Appl. Math., 21 (1971)) and was obtained as a particular family of Lagrangian distributions by Consul and Shenton (SIAM J. Appl. Math., 23 (1973)). Consul and Shenton also gave the probability generating function (p.g.f.) and proved many properties of the GNBD. Consul and Gupta (SIAM J. Appl. Math., 39 (1980)) proved that the parameter β must be either zero or 1≤ β ≤ θ^-1 for the GNBD to be a true probability distribution and proved some other properties. Numerous applications and properties of this model have been studied by various researchers. Considering two independent GNB variates X and Y, with parameters (m,β,θ) and (n,β,θ) respectively, the probability distribuition of D = Y-X and its p.g.f. and cumulant generating function have been obtained. A recurrence relation between the cumulants has been established and the first four cumulants, β₁ and β₂ have been derived. Also some moments of the absolute difference |Y-X| have been obtained.
