Documentation

scale Source #

Arguments

:: String	Name.
-> Int	Weight.
-> Lens' a Double	Instruction about which parameter to change.
-> Double	Shape.
-> Double	Scale.
-> Bool	Enable tuning.
-> Move a

Multiplicative move with Gamma distributed density.

scaleUnbiased Source #

Arguments

:: String	Name.
-> Int	Weight.
-> Lens' a Double	Instruction about which parameter to change.
-> Double	Shape.
-> Bool	Enable tuning.
-> Move a

Multiplicative move with Gamma distributed density. The scale of the Gamma distributions is set to (shape)^{-1}, so that the mean of the Gamma distribution is 1.0.
