GAMMADIST

Definition: GAMMADIST is a function that returns the gamma distribution for a specified set of parameters.

Syntax: =GAMMADIST(x, alpha, beta, [cumulative])

Situation: This formula is suitable when you need to find the gamma distribution for a specified set of parameters.

Example: If you have a random variable x with parameters alpha=2 and beta=3, and want to find the probability that x is less than or equal to 1, the formula =GAMMADIST(1, 2, 3, TRUE) can be used, which returns 0.5768.
