GAMMADIST

Calculates values for a gamma distribution.

Syntax:

GAMMADIST(x; α; λ; mode)

The gamma distribution is a family of continuous probability distributions, with two controlling parameters α and λ.

If mode is 0, GAMMADIST calculates the probability density function of the gamma distribution.

If mode is 1, GAMMADIST calculates the cumulative distribution function of the gamma distribution.

Example:

GAMMADIST(2; 1; 1; 1)

returns approximately 0.86.
