logMargDenNR
computes log marginal density using the Newton-Raftery approximation.
Note: this approximation can be influenced by outliers in the vector of log-likelihoods. Use
with care .
logMargDenNR(ll)
ll |
vector of log-likelihoods evaluated at length(ll) MCMC draws |
approximation to log marginal density value.
This routine is a utility routine that does not check the input arguments for proper dimensions and type.
