- Gamma( <Number α>, <Number β>, x )
- Creates cumulative density function (cdf) of gamma distribution with parameters α, β.
- Gamma( <Number α>, <Number β>, x, <Boolean Cumulative> )
- If Cumulative is true, creates cumulative distribution function of gamma distribution, otherwise creates pdf of gamma distribution.
- Gamma( <Number α>, <Number β>, <Variable Value v> )
- Calculates the value of cumulative distribution function of gamma distribution at v, i.e. the probability P(X≤v) where X is a random variable with gamma distribution given by parameters α, β.
- Note:Returns the probability for a given x-coordinate's value (or area under the gamma distribution curve to the left of the given x-coordinate).
