ddir: Dirichlet density

In mombf: Bayesian Model Selection and Averaging for Non-Local and Local Priors

Description

Evaluate the density of a Dirichlet distribution

Usage

ddir(x, q, logscale=TRUE)

Arguments

x	Vector or matrix containing the value at which to evaluate the density. If a matrix, the density is evaluated for each row. Rows are renormalized to ensure they add up to 1
q	Dirichlet parameters. Must have the same length as ncol(x), or length 1 (in which case a symmetric Dirichlet density is valuated)
logscale	For logscale==TRUE, dimom returns the natural log of the prior density

Value

Density of a Dirichlet(q) distribution evaluated at each row of x

library(mombf)
x= matrix(c(1/3,2/3,.5,.5),nrow=2,byrow=TRUE)
ddir(x,q=2)
