Introduction: Despite the advances in cardiovascular diseases, death caused by these diseases is still considered as the leading cause of mortality. In this study, some of the effective factors on the deaths caused by cardiovascular diseases were investigated Methods: This cross-sectional analytical study investigated the efficacy of Poisson regression models and negative binomial regres...
Various statistical methods have been used to measure the impact of treatment on chronic obstructive pulmonary disease (COPD) exacerbations. Poisson regression has recently been recommended as the appropriate method but the model does not satisfactorily account for variability between patients. In contrast, use of a negative binomial model, which corresponds to assuming a separate Poisson param...
The seemingly unrelated Poisson (SUP) model (King (1989a), see also Aptech (1994)) is a model for bior multi-variate counted outcomes. Correlation between equations is introduced through a convolution structure with a common additive factor. Previous economic applications include the joint analysis of voluntary and involuntary labour mobility (Jung and Winkelmann, 1993) and the number of recrea...
