### Usage

mvHSRFHyperpriorsGibbs(RealPos gs, RealPos[] ls, Real[] normals, RealPos zeta, Natural order, RealPos weight, Probability tuneTarget)

### Arguments

 gs : RealPos ( pass by reference) The global scale variable on which this move operates ls : RealPos[] ( pass by reference) The local scales variables on which this move operates. normals : Real[] ( pass by reference) The vector of Normal RVs defining the field zeta : RealPos (pass by value) The value controlling the shrinkage of the field. 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 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
