dirichlet: Dirichlet functions

In dirichlet: Dirichlet and Generalized Dirichlet Distribution functions

Description

pdf and random deviates of the Dirichlet distribution.

Usage

rdirichlet(n, alpha, allowZero=FALSE)
ddirichlet(x, alpha)

Arguments

alpha	The Dirichlet parameters. alpha > 0 unless allowZero=TRUE
n	number of observations
x	vector of quantiles. For x < 0 || x > 1 or if the sum of x is not equal to 1, zero will be returned for the density
allowZero	Indicator that zeros are allowed in the alpha vector and should be handled appropriately

Value

ddirichlet gives the density and rdirichlet generates random deviates.
