rdirichlet {grizbayr}

Random Dirichlet

Description

Randomly samples a vector of length n from a dirichlet distribution parameterized by a vector of alphas PDF of Gamma with scale = 1 : f(x)= 1/(Gamma(a)) x^(a-1) e^-(x)

Usage

rdirichlet(n, alphas_list)

Arguments

n

integer, the number of samples

alphas_list

Named List of Integers: parameters of the dirichlet, interpreted as the number of success of each outcome

Value

n x length(alphas) named tibble representing the probability of observing each outcome

Examples

rdirichlet(100, list(a = 20, b = 15, c = 60))
