ddirichlet_cc: Computes the 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 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

ddirichlet_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 density values.
