logMargDenNR {bayesm}

Compute Log Marginal Density Using Newton-Raftery Approx

Description

logMargDenNR computes log marginal density using the Newton-Raftery approximation.

Usage

logMargDenNR(ll)

Arguments

ll

vector of log-likelihoods evaluated at length(ll) MCMC draws

Value

Approximation to log marginal density value.

Warning

This approximation can be influenced by outliers in the vector of log-likelihoods; use with care. This routine is a utility routine that does not check the input arguments for proper dimensions and type.
