Gamma Command
From GeoGebra Manual
- Gamma[ <Number α>, <Number β>, x ]
- Creates probability density function (pdf) of Gamma distribution with parameters α, β.
- Gamma[ <Numerator Degrees of Freedom>, <Denominator Degrees of Freedom>, x, <Boolean Cumulative> ]
- If Cumulative is true, creates cumulative density 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).
CAS Syntaxes
In CAS View only following syntax is supported:
- 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.
