The geometric distribution is a special case of the negative binomial distribution. It deals with the number of trials required for a single success. Thus, the geometric distribution is negative binomial distribution where the number of successes (r) is equal to 1.
Distributions related to the normal distribution Three important distributions: Chi-square (˜2) distribution. tdistribution. Fdistribution. Before we discuss the ˜2;t, and F distributions here are few important things about the gamma distribution. The gamma distribution is useful in modeling skewed distributions for variables that are not negative.
Poisson Distribution. A Poisson distribution is the probability distribution that results from a Poisson experiment. Attributes of a Poisson Experiment. A Poisson experiment is a statistical experiment that has the following properties: The experiment results in outcomes that can be classified as successes or failures.
