This paper explores the influence of demographic and spatial variables on individual participation and consumption of wildland area recreation. Data from the National Survey on Recreation and the Environment are combined with geographical information system-based distance measures to develop...

On the basis of a negative binomial sampling scheme, we consider a uniformly most accurate upper confidence limit for a small but unknown proportion, such as the proportion of defectives in a manufacturing process. The optimal stopping rule, with reference to the twin criteria of the expected...

Although the world wide global polio eradication program aimed at exterminating the disease by the year 2003, seven countries including India are still considered to be polio endemic. India witnessed a polio explosion during the year 2002. In recent years there is definite evidence in favor of...

In this paper we develop an empirical model for transnational terrorist activity for a panel consisting of 139 countries over the period 1985-1998. Essentially, we attempt to sketch the profile of the average terrorist attack venue. Our findings suggest that the terrorist attack venue is, on...

This paper identifies determinants of extensive (i.e., number of firms) and intensive (i.e., average exports per firm) trade margins, using state-level exports to 187 countries. A standard negative binomial count model is used to handle the issues of non-trading pairs and overdispersion in the...

Given a sample from a finite population partitioned into classes, we consider estimating the distribution of the class frequencies. We propose first to estimate certain moments of this distribution, assuming Poisson sampling with unequal inclusion probabilities, and then to adapt these estimates...

This article studies the various mechanisms by which democracy affects transnational terrorism. New theoretical mechanisms are identified that either complement or encompass existing arguments. Different effects of democracy on transnational terrorism are assessed for a sample of about 119...

Poisson and negative binomial regression methods are used to analyze the monthly time series data to determine the effects of introducing an integrated security management system including closed-circuit television (CCTV), door alarm monitoring, proximity card access, and emergency call boxes to...

Simultaneous estimators of the dispersion parameters in m negative binomial distributions with known success probabilities are shown to dominate the usual estimator under squared error loss by shrinking it toward either a fixed or a data-driven point.
