This paper is concerned with the estimation of the covariance parameter of the bivariate Poisson distribution. It is shown that the method of moments has low efficiency for distributions with ...

The Canadian Journal of Statistics / La Revue Canadienne de Statistique Let Xi be the number of outcomes in class Ci,i=0,... ,k, during n independent possibly non-identical trials. If class C0 has ...

For binomial and Poisson distributions, the scale parameter has a value of 1. The variance of Y is for the binomial distribution and for the Poisson distribution. Overdispersion occurs when the ...

An understanding of a material's microscopic architecture is important to improve its mechanical properties. Poisson's ratio, which celebrates its bicentenary this year, continues to provide a good ...
