Definition: Gamma distribution is a distribution that arises naturally in processes for which the waiting times between events are relevant. It can be thought of as a waiting time between Poisson distributed events. Probability density function: The waiting time until the hth Poisson event with a rate of change Î» is.
Note that, as usual, there are an infinite number of possible gamma distributions because there are an infinite number of possible Î¸ and Î± values. That's, again, why this page is called Gamma Distributions (with an s) and not Gamma Distribution (with no s). Because each gamma distribution depends on the value of Î¸ and Î±, it shouldn't be surprising that the shape of the probability distribution changes as Î¸ and Î± change.
