Constructor Detail

DistBernoulli

public DistBernoulli(StreamInterface stream,
             double p)

constructs a new Bernoulli distribution. Random occurence with two possible outcomes; used to generate other discrete random variates.

Parameters:

stream - is the stream

p - the p-value of a Bernoulli distribution

Method Detail

draw

public long draw()

draws the next value from the Bernoulli distribution. More information on this distribution can be found at < a href="http://mathworld.wolfram.com/BernoulliDistribution.html"> http://mathworld.wolfram.com/BernoulliDistribution.html .

Specified by:

draw in class DistDiscrete

Returns:

the next value {0,1}.

probability

public double probability(int observation)

Description copied from class: DistDiscrete

returns the propbability of the observation in this particular distribution.

Specified by:

probability in class DistDiscrete

Parameters:

observation - the discrete observation.

Returns:

double the probability.
