## mvRandomGeometricWalk

### Usage

mvRandomGeometricWalk(Integer x, Probability alpha, Bool tune, RealPos weight, Probability tuneTarget)

### Arguments

 x : Integer ( pass by reference) The variable on which this move operates. alpha : Probability (pass by value) The success probability of the geometric distribution. Default : 0.5 tune : Bool (pass by value) Should we tune the success probability during burnin? Default : TRUE 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
