In Compositional: Compositional Data Analysis
Dirichlet random values simulation R Documentation
Dirichlet random values simulation
Description
Dirichlet random values simulation.
Usage
rdiri(n, a)
Arguments
n
The sample size, a numerical value.
a
A numerical vector with the parameter values.
Details
The algorithm is straightforward, for each vector, independent gamma values are generated and then divided by their total sum.
Value
A matrix with the simulated data.
Author(s)
