background : so far, several studies were conducted to estimate the prevalence of cigarette smoking in iran, but none of them used a statistical model to deal with unobserved smokers. the present study planned to estimate the accurate prevalence of cigarette smoking using mixture of truncated poisson distribution. methods : a cross-sectional study was conducted in hamadan, west of iran in 2009,...

In this paper, we will study compatible triples on Lie algebroids. Using a suitable decomposition for a Lie algebroid, we construct an integrable generalized distribution on the base manifold. As a result, the symplectic form on the Lie algebroid induces a symplectic form on each integral submanifold of the distribution. The induced Poisson structure on the base manifold can be represented by m...

the interaction of radiation with cells and tissues has a random nature. therefore, understanding the random nature of cell killing that is determined by poisson distribution statistics is an essential point in education of radiation biology. radbiostat is a newly developed educational matlab-based software designed for computer-assisted learning of the target theory in radiation biology. altho...
