funnel.dist: Funnel distribution object

Description Details References See Also


A distribution object for Radford Neal's funnel distribution


funnel.dist represents the funnel distribution described by Neal (2003, p. 732). It is a ten-dimensional distribution on the reals, with:

v~N(0,3^2), x[k]~N(0,exp(v)) for k=1,...,9

The state space is (v,x[1],x[2],...,x[9]). The name comes from the funnel-shaped two dimensional marginal distributions (v,x[k]).

This object is intended as a demonstration to be passed to compare.samplers.
