Constructor Detail

BernoulliDistribution

public BernoulliDistribution(double p)
This general constructor creates a new Bernoulli distribution with a specified parameter.

Parameters:
p - the probaiblity of 1

BernoulliDistribution

public BernoulliDistribution()
This default constructor creates a new Bernoulli distribution with parameter p = 0.5.

Method Detail

getMaxDensity

public double getMaxDensity()
This method returns the maximum value of the probability density function.

Overrides:
getMaxDensity in class BinomialDistribution
Returns:
the maximum value of the probability density function

setTrials

public void setTrials(int n)
This method sets the number of trials, which is always 1.

Overrides:
setTrials in class BinomialDistribution
Parameters:
n - the number of trials.

toString

public java.lang.String toString()
This method returns a string that gives the name of the distribution and the values of the parameters.

Overrides:
toString in class BinomialDistribution
Returns:
a string giving the name of the distribution and the values of the parameters
