mvShrinkExpandScale
Usage
mvShrinkExpandScale(RealPos[] x, RealPos sd, RealPos lambda, Bool tune, RealPos weight, Probability tuneTarget)
Arguments
| x : | RealPos[] (<deterministic> pass by reference) |
| The variable on which the move operates. | |
| sd : | RealPos (<stochastic> pass by reference) |
| The standard deviation parameter if available. | |
| Default : NULL | |
| lambda : | RealPos (pass by value) |
| The scaling factor (strength) of the proposal. | |
| Default : 1 | |
| tune : | Bool (pass by value) |
| Should we tune the scaling factor during burnin? | |
| Default : TRUE | |
| weight : | RealPos (pass by value) |
| The weight determines the relative frequency with which this move will be attempted. For details, see the description of the 'moveschedule' parameter on the documentation page for 'mcmc()'. | |
| Default : 1 | |
| tuneTarget : | Probability (pass by value) |
| The acceptance probability targeted by auto-tuning. | |
| Default : 0.44 |
