14 p, 148.9 KB Verifying compliance with ballast water standards : a decision-theoretic approach / Costa, Eliardo G. ; Paulino, Carlos Daniel ; Singer, Julio M.
We construct credible intervals to estimate the mean organism (zooplankton and phytoplankton) concentration in ballast water via a decision-theoretic approach. To obtain the required optimal sample size, we use a total cost minimization criterion defined as the sum of the sampling cost and the Bayes risk either under a Poisson or a negative binomial model for organism counts, both with a gamma prior distribution. [...]

12 p, 210.0 KB Statistical modeling of warm-spell duration series using hurdle models / Rydén, Jesper (Uppsala University. Department of Mathematics)
Regression models for counts could be applied to the earth sciences, for instance when studying trends of extremes of climatological quantities. Hurdle models are modified count models which can be regarded as mixtures of distributions. [...]

14 p, 107.2 KB Some discrete exponential dispersion models : poisson-tweedie and hinde-demétrio classes / Kokonendji, Célestin C. (University of Pau-LMA) ; Dossou-Gbété, Simplice (University of Pau-LMA) ; Demétrio, Clarice Garcia Borges (University of S˜ao Paulo)
In this paper we investigate two classes of exponential dispersion models (EDMs) for overdispersed count data with respect to the Poisson distribution. The first is a class of Poisson mixture with positive Tweedie mixing distributions. [...]
