Constructor Detail

GeometricDistribution

public GeometricDistribution()

Default builder. Creates a geometric distribution with parameter P=0.0

GeometricDistribution

public GeometricDistribution(double p)

Builder. Creates a geometric distribution with parameter P

Parameters:

p - P parameter

GeometricDistribution

public GeometricDistribution(GeometricDistribution old)

Copy constructor Creates a copy of a given geometric distribution

Parameters:

old - geometric distribution to copy

Method Detail

setP

public void setP(double value)

Sets the P parameter. Only works if P is in [0.0,1.0]

Parameters:

value - P parameter value

getP

public double getP()

Gets the P parameter value

Returns:

value of P

computeProbability

public double computeProbability(double value)

Computes mass probability at a given point of the geometric distribution. Value given is converted to integer before computing probability.

Specified by:

computeProbability in interface Distribution

Parameters:

value - point selected

Returns:

mass probability at 'value'

computeCumulativeProbability

public double computeCumulativeProbability(double value)

Computes cumulative probability at a given point of the geometric distribution. Value given is converted to integer before computing probability.

Specified by:

computeCumulativeProbability in interface Distribution

Parameters:

value - point selected

Returns:

cumulative probability at 'value'

toString

public java.lang.String toString()

To String method.

Overrides:

toString in class java.lang.Object

Returns:

string representation of the distribution
