Class IDistMappedCoupler<T extends org.apache.commons.math3.distribution.IntegerDistribution>

java.lang.Object

io.virtdata.mappers.mapped_discrete.IDistMappedCoupler<T>

All Implemented Interfaces:

LongUnaryOperator

public class IDistMappedCoupler<T extends org.apache.commons.math3.distribution.IntegerDistribution>
extends Object
implements LongUnaryOperator

Generates a long value representing a sampled value from a cumulative density function for a binomial curve.

This class does nothing to handle randomness or the need to choose over the possible interval pseudo-randomly. It simply provides the transform between the "U" unit-interval value that you would get from that phase and the resulting value on the cumulative density curve.

Specifically, the input value is not in actual "U" unit-interval form. It is instead a value from the set of positive long values.
