rPoisson¶
- rPoisson(*args)¶
Realization of a Poisson distribution.
- Parameters:
- lambdafloat,
The intensity of the Poisson distribution.
- sizeint
The number of realizations to generate.
- Returns:
- realizationsint or
Indices
The realizations of the distribution.
- realizationsint or
Notes
For the small values of , we use the method of inversion by sequential search described in [devroye1986] and with the important errata in [devroye1986b]. For the large values of , we use the ratio of uniform method described in [stadlober1990].
Examples
>>> import openturns as ot >>> ot.RandomGenerator.SetSeed(0) >>> r = ot.DistFunc.rPoisson(5.0) >>> r = ot.DistFunc.rPoisson(5.0, 10)
