ddirichlet: Compute density of Dirichlet distribution

Description

This function computes the density of a Dirichlet distribution.

Usage

ddirichlet(x, concentration, log = FALSE)

Value

A numeric, the density value.

Arguments

x

A numeric, a weight vector of length p. Each vector element must be between 0 and 1. The sum of the vector elements must be 1.

concentration

A numeric, the concentration vector of length p.

log

A logical, if TRUE the logarithm of the density value is returned. By default, log = FALSE.

Examples

x <- c(0.5, 0.3, 0.2)
concentration <- 1:3
ddirichlet(x = x, concentration = concentration)
ddirichlet(x = x, concentration = concentration, log = TRUE)
