Dirichlet distribution

Usage

ddirichlet(x, alpha, log = TRUE)

Arguments

x

vector or matrix of quantiles

alpha

vector or matrix of shape parameters

log

logical; if TRUE, densities \(p\) are returned as \(\log(p)\).

Value

ddirichlet gives the density.

Details

This implementation of ddirichlet allows for automatic differentiation with RTMB.

Examples

ddirichlet(c(0.2, 0.3, 0.5), c(1, 2, 3))
