Constructor Summary

DieDistribution()
This default constructor creates a new fair die distribution.

DieDistribution(double[] p)
This general constructor creates a new die distribution with specified probabilities.

DieDistribution(int n)
This special constructor creates a new die distribution of a special type (1-6 flat, 2-5 flat, 3-4 flat, skewed left, skewed right, or fair).

Method Summary

void	setParameters(double a, double b, double w, double[] p) This method ensures that the finite distribution parameters are not changed to inappropriate values.
void	setProbabilities(double[] p) This method sets the probabilities.
void	setProbabilities(int n) This method specifies the probabilities for the special types (fair, 1-6 flat, 2-5 flat, 3-4 flat, skewed left, or skewed right).
java.lang.String	toString() This method returns a string that gives the name of the distribution and the values of the parameters.

Constructor Detail

DieDistribution

public DieDistribution(double[] p)

This general constructor creates a new die distribution with specified probabilities.

Parameters:

p - the array of probabilities

DieDistribution

public DieDistribution(int n)

This special constructor creates a new die distribution of a special type (1-6 flat, 2-5 flat, 3-4 flat, skewed left, skewed right, or fair).

Parameters:

n - the type of distribution

DieDistribution

public DieDistribution()

This default constructor creates a new fair die distribution.

Method Detail

setProbabilities

public void setProbabilities(int n)

This method specifies the probabilities for the special types (fair, 1-6 flat, 2-5 flat, 3-4 flat, skewed left, or skewed right).

Parameters:

n - the type of distribution

setProbabilities

public void setProbabilities(double[] p)

This method sets the probabilities. The length of the array must be 6.

Overrides:

setProbabilities in class FiniteDistribution

Parameters:

p - the array of probabilities

setParameters

public void setParameters(double a,
                          double b,
                          double w,
                          double[] p)

This method ensures that the finite distribution parameters are not changed to inappropriate values.

Overrides:

setParameters in class FiniteDistribution

Parameters:

a - the lower value of the domain

b - the upper value of the domain

w - the step size of the domain

p - the array of probabilities

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 FiniteDistribution

Returns:

a string giving the name of the distribution and the values of the parameters
