Erlang Command
From GeoGebra Manual
- Erlang[ <Shape>, <Rate>, x ]
- Creates probability density function (pdf) of Erlang distribution with parameters shape k and rate λ.
- Erlang[ <Shape>, <Rate>, x, <Boolean Cumulative> ]
- If Cumulative is true, creates cumulative distribution function of Erlang distribution, otherwise creates pdf of Erlang distribution.
- Erlang[ <Shape>, <Rate>, <Variable Value> ]
- Calculates the value of cumulative distribution function of Erlang distribution at variable value v, i.e. the probability P(X ≤ v) where X is a random variable with Erlang distribution given by parameters shape k and rate λ.
- Note: Returns the probability for a given x-coordinate's value (or area under the Erlang distribution curve to the left of the given x-coordinate).
