MPE.GaussianNIW {bbricks}R Documentation

Mean Posterior Estimate (MPE) of a "GaussianNIW" object

Description

Generate the MPE of (mu,Sigma) in following GaussianNIW structure:

mu,Sigma|m,k,v,S \sim NIW(m,k,v,S)

x|mu,Sigma \sim Gaussian(mu,Sigma)

Where NIW() is the Normal-Inverse-Wishart distribution, Gaussian() is the Gaussian distribution. See ?dNIW and dGaussian for the definitions of these distribution.
The model structure and prior parameters are stored in a "GaussianNIW" object.
The MPE estimates are:

Usage

## S3 method for class 'GaussianNIW'
MPE(obj, ...)

Arguments

obj

A "GaussianNIW" object.

...

Additional arguments to be passed to other inherited types.

Value

A named list, the MPE estimate of mu and Sigma.
