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 ...
Widely used in engineering education and industrial practice, this handbook provides a comprehensive, systematic presentation of today's reliability engineering for optimized design engineering of ...
In particular, we will motivate the need for GLMs; introduce the binomial regression model ... and when that count is thought to depend on a set of predictors, we can use Poisson regression as a model ...
The book then gives an in-depth analysis of Poisson regression and an evaluation of the meaning and nature of overdispersion, followed by a comprehensive analysis of the negative binomial distribution ...
The scale parameter is 1 for Poisson and binomial distributions. SAS/INSIGHT software provides different scale parameter estimates for normal, inverse Gaussian, and gamma distributions: Note You can ...
