View source: R/priorConRatio.R

Description

This function computes the Prior Constant Ratio Approximation that appears in the Metropolis Odds as propose in Wang and Li, in Efficient Gaussian graphical Model determination under G-Wishart prior distributions.

bPrior

Prior dedrees of freedom. Defaults to 3.

DPrior

Prior location SPD Matrix. Defaults to the identity matrix.

i

Row index.

j

Column index.

Value

Logarithm of the Prior Constant Ratio Approximation.
