Constructor Detail

DistPoisson

public DistPoisson(double lambda)

Create a Poisson distribution instance.

Parameters:

lambda - The lambda value (mean) for the distribution.

Since:

0.2

Method Detail

setLambda

public void setLambda(double lambda)

Change (set) the lambda value of the distribution.

Parameters:

lambda - The new lambda value (distribution mean).

getLambda

public double getLambda()

Get the distribution's lambda value (mean).

Returns:

The lambda value.

toString

public java.lang.String toString()

Custom toString implementation.

Specified by:

toString in class DistributionDiscrete

Returns:

A string representation of the distribution; e.g., "Poisson(1.0)".

Since:

0.2

createUnregisteredCopy

public Distribution createUnregisteredCopy()

Create an unregistered copy of this distribution.

Specified by:

createUnregisteredCopy in class Distribution

Returns:

The unregistered copy. (This will need casting as appropriate.)

Since:

0.2
