Enclosing class:

Discretes

public class Discretes.Shifted
extends Discretes

This UnParameterised Model of Discretes shifted by +offset. A shifted UnParameterised Model estimates or otherwise creates a shifted Model. Position parameters, such as mean μ, are in effect moved to μ+offset. E.g., Poisson1 = Poisson0.shifted(1) models ints n≥1. Note that shifting a Bounded Model may reduce the data-space. Also see Discretes.shifted(int) and Discretes.M.shifted(int).
2020: See UPModel.Transform for a more general way of transforming any Model using a Function.

Field Detail

offset

public final int offset

The offset adjustment, as an int.

Constructor Detail

Shifted

public Shifted(Value dp)

The problem defining parameter, dp, is the offset Int.

Method Detail

stats

public Value stats(Vector ds,
                   int lo,
                   int hi)

Return sufficient statistics, ss=stats(ds,lo,hi), for a shifted (-offset) data-set ds[lo,hi).

Specified by:

stats in class UPModel

stats

public Value stats(boolean add,
                   Value ss0,
                   Value ss1)

Description copied from class: UPModel

Combine sufficient statisticses 'ss0' and 'ss1' additively (add=true), or remove ss1 from ss0 (add=false). Also see stats(ds,lo,hi).

Specified by:

stats in class UPModel

estimator

public UPModel.Est estimator(Value ps)

The shifted Estimator estimates a shifted Model.

Overrides:

sp2Model

public Discretes.M sp2Model(double msg1,
                            double msg2,
                            Value sp)

Description copied from class: UPModel

Given two-part message lengths msg1 & msg2, and statistical parameter sp, return a fully parameterised M-Model. If 'this' UPModel produces a Model m, then sp2Model(m.msg1(), m.msg2(), m.statParams()) must be equivalent to m. Also see apply(sp).

Specified by:

sp2Model in class Discretes

toString

public java.lang.String toString()

Description copied from class: UPModel

Return a String representation of 'this' UnParameterised Model, including its problem-defining parameters.

Overrides:
