Constructor Summary

BinomialRandomNDistribution()
This default constructor: creates a new randomized binomial distribution with probability of success 0.5 and the uniform distribution on {1, 2, 3, 4, 5, 6} for the number of trials

BinomialRandomNDistribution(Distribution d, double p)
This general constructor creates a new randomized binomial distribution with a specified probability of success and a specified distribution for the number of trials

BinomialRandomNDistribution(double p)
Special constructor: creates a new randomized binomial distribution with a specified probability of success and the uniform distribution on {1, 2, 3, 4, 5, 6} for the number of trials

Method Summary

double	getDensity(double x) The getDensity method is abstract and must be overridden for any specific distribuiton
double	getMean() This method returns a default approximate mean, based on the finite set of domain values.
double	getVariance() This method returns a default approximate variance.
void	setParameters(Distribution d, double p) Set the parameters: the distribution for the number of trials and the probability of success
double	simulate() This method computes a default simulation of a value from the distribution, as a random getQuantile.

Constructor Detail

BinomialRandomNDistribution

public BinomialRandomNDistribution(Distribution d,
                                   double p)

This general constructor creates a new randomized binomial distribution with a specified probability of success and a specified distribution for the number of trials

BinomialRandomNDistribution

public BinomialRandomNDistribution(double p)

Special constructor: creates a new randomized binomial distribution with a specified probability of success and the uniform distribution on {1, 2, 3, 4, 5, 6} for the number of trials

BinomialRandomNDistribution

public BinomialRandomNDistribution()

This default constructor: creates a new randomized binomial distribution with probability of success 0.5 and the uniform distribution on {1, 2, 3, 4, 5, 6} for the number of trials

Method Detail

setParameters

public void setParameters(Distribution d,
                          double p)

Set the parameters: the distribution for the number of trials and the probability of success

getDensity

public double getDensity(double x)

Description copied from class: Distribution

The getDensity method is abstract and must be overridden for any specific distribuiton

Specified by:

getDensity in class Distribution

getMean

public double getMean()

Description copied from class: Distribution

This method returns a default approximate mean, based on the finite set of domain values. This method should be overriden if the mean is known in closed form

Overrides:

getMean in class Distribution

getVariance

public double getVariance()

Description copied from class: Distribution

This method returns a default approximate variance. This method should be overriden if the variance is known in closed form

Overrides:

getVariance in class Distribution

simulate

public double simulate()

Description copied from class: Distribution

This method computes a default simulation of a value from the distribution, as a random getQuantile. This method should be overridden if a better method of simulation is known.

Overrides:

simulate in class Distribution
