DiscreteUniformDistribution

public DiscreteUniformDistribution()

Method Detail

initialize

public void initialize()

Description copied from class: Distribution

used for some subclass to initialize before being used

Overrides:

initialize in class Distribution

valueChanged

public void valueChanged(java.util.Observable o,
                java.lang.Object arg)

Overrides:

valueChanged in class Distribution

setParameters

public void setParameters(double a,
                 double b,
                 double w)

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

getMaxDensity

public double getMaxDensity()

Description copied from class: Distribution

This method returns the largest (finite) value of the getDensity function on the finite set of domain values. This method should be overridden if the maximum value is known in closed form

Overrides:

getMaxDensity 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

getOnlineDescription

public java.lang.String getOnlineDescription()

This method returns an online description of this distribution.

Overrides:

getOnlineDescription in class Distribution
