rBeta: Random generator from the beta distribution

In FlexReg: Regression Models for Bounded Continuous and Discrete Responses

Random generator from the beta distribution

Description

The function generates random values from the beta distribution with a mean-precision parameterization, or from the augmented beta distribution.

Usage

rBeta(n, mu, phi, q0 = NULL, q1 = NULL)

Arguments

n	the number of values to generate. If length(n) > 1, the length is taken to be the number required.
mu	the mean parameter. It must lie in (0, 1).
phi	the precision parameter. It must be a real positive value.
q0	the probability of augmentation in zero. It must lie in (0, 1). In case of no augmentation, it is NULL (default).
q1	the probability of augmentation in one. It must lie in (0, 1). In case of no augmentation, it is NULL (default).

Value

A vector of length n.
