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

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

getParameter

public double getParameter(int i)

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

getQuantile

public double getQuantile(double p)

Description copied from class: Distribution

This method computes an approximate getQuantile function. This should be overriden if the getQuantile function is known in closed form

Overrides:

getQuantile in class Distribution

CDF

public double CDF(double x)

getName

public java.lang.String getName()

Specified by:

getName in interface Pluginable

Overrides:

getName in class Distribution

getOnlineDescription

public java.lang.String getOnlineDescription()

This method returns an online description of this distribution.

Overrides:

getOnlineDescription in class Distribution
