mvGMRFHyperpriorGibbs

Usage

mvGMRFHyperpriorGibbs(RealPos x, Real[] normals, RealPos zeta, Natural order, RealPos weight, Probability tuneTarget)

Arguments

x : RealPos (<stochastic> pass by reference)
The variable on which this move operates.
normals : Real[] (<deterministic> pass by reference)
The vector of Normal RVs defining the field
zeta : RealPos (pass by value)
The value controlling the shrinkage of the field, a scale by which x is multiplied, effectively making x ~ halfCauchy(0,zeta).
order : Natural (pass by value)
The order of this GMRF model, first (1) or second (2). Defaults to first order.
Default : 1
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
