Method Detail

getDomain

java.util.Set<? extends DataType> getDomain()

Returns an object that allows an iteration through the domain (x-axis, independent variable) of the Distribution

Returns:

Collection that enumerates each value that the domain can take

getDomainSize

int getDomainSize()

Gets the size of the domain.

Returns:

The size of the domain.

getProbabilityFunction

ProbabilityMassFunction<DataType> getProbabilityFunction()

Description copied from interface: ComputableDistribution

Gets the distribution function associated with this Distribution, either the PDF or PMF.

Specified by:

getProbabilityFunction in interface ComputableDistribution<DataType>

Returns:

Distribution function associated with this Distribution.
