The Dirichlet Distribution

Density function and random number generation for the dirichlet distribution with shape parameter vector alpha.

ddirichlet(x, alpha, log = FALSE)

rdirichlet(n, alpha)

`x`	Matrix of quantiles. Each row corresponds to one probability vector.
`alpha`	Matrix of positive shape parameters. Each row corresponds to one probability vector.
`log`	Logical; If `TRUE`, values are returned on the log scale.
`n`	Number of samples to draw from the distribution.

See vignette("brms_families") for details on the parameterization.
