:: Double | Shape. |
-> Double | Scale. |
-> PName | Name. |
-> PWeight | PWeight. |
-> Tune | Enable tuning. |
-> Proposal Double |
Multiplicative proposal with Gamma distributed kernel.
Multiplicative proposal with Gamma distributed kernel.
The scale of the Gamma distributions is set to (shape)^{-1}, so that the mean of the Gamma distribution is 1.0.

-> PName | Name. |
-> PWeight | PWeight. |
-> Tune | Enable tuning. |
-> Proposal (Double, Double) |
Multiplicative proposal with Gamma distributed kernel.
The two values are scaled contrarily so that their product stays constant. Contrary proposals are useful when parameters are confounded.
