lddirichlet_cc: Computes the log density of the Dirichlet distribution

In simonsays1980/finmix: An R package for Bayesian estimation of finite mixture distributions

Description

For each shape and rate parameter pair the log-Dirichlet density is computed. Inside the function the unsafe access functions of Armadillo at() and unsafe_col() are used, so now boundary check is performed. In each step the lgammafn() function from Rcpp's R namespace is used. At this time unused.

Usage

lddirichlet_cc(values, par)

Arguments

values	A matrix of dimension M x K for which the log-density should be calculated.
par	A vector of dimension K x 1 containing the Dirichlet parameters.

Value

A vector of Dirichlet log-density values.
