mvBetaProbability(Probability x, RealPos delta, RealPos offset, Bool tune, RealPos weight, Probability tuneTarget)


x : Probability (<stochastic> pass by reference)
The variable this move operates on.
delta : RealPos (pass by value)
The concentration parameter on the current value.
Default : 1
offset : RealPos (pass by value)
The offset used to center proposals around 0.5.
Default : 0
tune : Bool (pass by value)
Should we tune the concentration parameter 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
