DistFunc_logdBinomial

DistFunc_logdBinomial(n, p, k)

Logarithm of the probability function of a binomial distribution.

Parameters

nint,

The number of trials

pfloat,

The success probability of each trial

kint

The number of success.

Returns

logpfloat

The natural logarithm of the probability to get successes.

Notes

This method implements Loader’s algorithm, the fast and accurate method described in [loader2000], with the further improvements mentioned in [dimitriadis2016].

Examples

>>> import openturns as ot
>>> p = ot.DistFunc.logdBinomial(5, 0.2, 2)
