DistBernoulli

class pydsol.core.distributions.DistBernoulli(stream: StreamInterface, p: float)

Bases: DistDiscrete

The Bernoulli distribution is a discrete distribution function with a single trial with a probability p for success (X = 1) and a probability 1-p for failure (X = 0).

__init__(stream: StreamInterface, p: float)

Constructs a new Bernoulli distribution, with p as the probability for success (X=1), where failure is associated with X=0.

Parameters:

• stream (StreamInterface) – the random stream to use for this distribution

• p (float) – the probability for success of the Bernoulli distribution

Raises:

• TypeError – when stream is not implementing StreamInterface:

• TypeError – when p is not a float:

• ValueError – when p < 0 or p > 1:

draw() → int

Draw a value from the Bernoulli distribution, where 1 denotes success (probability p) and 0 indicates failure (probability 1 - p).

probability(observation: int) → float

Returns the probability of the observation for the distribution.

property p: float

Return the parameter value p

property stream: StreamInterface

Return the current random stream for this distribution.
