Description

Create the trimodal distribution as in Liang, Liu and Caroll, 2007: Stochastic approximation in Monte Carlo computation.

Usage

1

Details

This distribution is a mixture of three bivariate Gaussian distributions. Their covariance matrices are such that an adaptive MCMC algorithm which proposal variance adapts to one of the component, will likely fail to explore the others.

Value

The function returns an object of class target, with a name, a dimension, a function giving the log density, a function to generate sample from the distribution, parameters of the distribution, and a function to draw init points for the MCMC algorithms.
