Dirichlet sampler — rdir • countSTAR

Compute one Monte Carlo draw from a Dirichlet distribution

Usage

rdir(params)

Arguments

params: the vector of (nonnegative) Dirichlet parameters

Value

the vector of the Dirichlet draw on the simplex

Details

This function computes one draw from a Dirichlet distribution. The output is on a simplex (nonnegative, sum to one) and has the same length as the input params.

Examples

# Example draw:
rdir(params = c(1,2,3))
#> [1] 0.3144499 0.3006112 0.3849389
