Understanding and Choosing the Right Probability Distributions

WebPoisson , robust , ML , Quasi-likelihood , Negative binomial ,GLM. INTRODUCTION The Poisson distribution is the most commonly used probability distribution for counting data. Allows for zero counts since it adjusts for the positive skewness inherent in count data[10], and is simple to use and interpret, the Poisson distribution is preferred. WebThe binomial distribution in this case will be symmetric, reflecting the even odds; as the probabilities shift from even odds, the distribution will get more skewed.
