mvRandomDive

The multiplicative proposal of Dutta 2012, allows for long-distance moves. Useful for fat-tailed distributions, possibly for bimoodal distributions. Variables on [0,infinity) are log-transformed for proposals.

Usage

mvRandomDive(Real x, RealPos delta, Bool tune, RealPos weight, Probability tuneTarget)

Arguments

x : Real (<stochastic> pass by reference)
The variable on which this move operates.
delta : RealPos (pass by value)
The tuning parameter, larger values for bolder moves.
Default : 1
tune : Bool (pass by value)
Should we tune the window size during burnin?
Default : TRUE
weight : RealPos (pass by value)
The weight determines the relative frequency with which this move will be attempted. For details, see the description of the 'moveschedule' parameter on the documentation page for 'mcmc()'.
Default : 1
tuneTarget : Probability (pass by value)
The acceptance probability targeted by auto-tuning.
Default : 0.44
