mvCorrelationMatrixElementSwap - Correlation Matrix element swap move.
Swaps elements i and j of the correlation matrix (i != j).
Usage
mvCorrelationMatrixElementSwap(MatrixReal x, RealPos weight)
Arguments
| x : | MatrixReal (<stochastic> pass by reference) |
| The variable on which this move operates. | |
| 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 |
Example
# we draw a correlation matrix from an LKJ distribution
R ~ dnLKJ(eta=1, dim=5)
# we specify an element swap move
moves[1] = mvCorrelationMatrixElementSwap(R)
