Proposes a move in state space.
Scales a parameter or a complete beast.tree (depending on which of the two is specified.
tree, parameter, scaleFactor, scaleAll, scaleAllIndependently, degreesOfFreedom, indicator, rootOnly, optimise, upper, lower, weight
| type: beast.evolution.tree.Tree |
| if specified, all beast.tree divergence times are scaled |
| Either this, or parameter needs to be specified |
| type: beast.core.parameter.RealParameter |
| if specified, this parameter is scaled |
| Either this, or tree needs to be specified |
| type: java.lang.Double |
| scaling factor: range from 0 to 1. Close to zero is very large jumps, close to 1.0 is very small jumps. |
| Optional input. Default: 0.75 |
| type: java.lang.Boolean |
| if true, all elements of a parameter (not beast.tree) are scaled, otherwise one is randomly selected |
| Optional input. Default: false |
| type: java.lang.Boolean |
| if true, all elements of a parameter (not beast.tree) are scaled with a different factor, otherwise a single factor is used |
| Optional input. Default: false |
| type: java.lang.Integer |
| Degrees of freedom used when scaleAllIndependently=false and scaleAll=true to override default in calculation of Hasting ratio. Ignored when less than 1, default 0. |
| Optional input. Default: 0 |
| type: beast.core.parameter.BooleanParameter |
| indicates which of the dimension of the parameters can be scaled. Only used when scaleAllIndependently=false and scaleAll=false. If not specified it is assumed all dimensions are allowed to be scaled. |
| Optional input |
| type: java.lang.Boolean |
| scale root of a tree only, ignored if tree is not specified (default false) |
| Optional input. Default: false |
| type: java.lang.Boolean |
| flag to indicate that the scale factor is automatically changed in order to achieve a good acceptance rate (default true) |
| Optional input. Default: true |
| type: java.lang.Double |
| Upper Limit of scale factor |
| Optional input. Default: 0.99999999 |
| type: java.lang.Double |
| Lower limit of scale factor |
| Optional input. Default: 1.0E-8 |
| type: java.lang.Double |
| weight with which this operator is selected |
