DPTreePosterior: D-P tree posterior updating from a single copula observation.

Description

DPTreePosterior returns the D-P tree posterior given input copula data.

Usage

DPTreePosterior(x, prior, w = 1)

Arguments

x

An array of length 2. Single copula data observation. Each element should be between 0 and 1.

prior

A list. Should be in same format as returned from DPTreePrior.

w

A positive number. Weight of data for posterior updating. Default 1.

Value

A list.

a

An array containing the hyperparameters of D-P trees.
