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


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).
weight : RealPos (pass by value)
The weight how often on average this move will be used per iteration.
Default : 1
tuneTarget : Probability (pass by value)
The acceptance probability targeted by auto-tuning.
Default : 0.44
