## mvGraphFlipEdge

### Usage

mvGraphFlipEdge(MatrixRealSymmetric x, Probability p, Natural[][] edges, Bool tune, RealPos weight, Probability tuneTarget)

### Arguments

 x : MatrixRealSymmetric ( pass by reference) The variable on which this move operates. p : Probability (pass by value) The probability of flipping each edge in edges (min flips == 1). Default : 0 edges : Natural[][] (pass by reference) A vector of [i,j] edges to target with this proposal. An empty vector is interpretted as the full list of edges. Default : [ ] tune : Bool (pass by value) Should we tune the scaling factor 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
