rBeta_mu: Random generator from the beta distribution

In FlexReg: Regression Models for Bounded and Binomial 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_mu(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 of the beta distribution. It must lie in (0, 1).
phi	the precision parameter of the Beta distribution. It must be a positive real value.
q0	the probability of augmentation in zero. It must lie in (0, 1). In case of no augmentation is NULL (default).
q1	the probability of augmentation in one. It must lie in (0, 1). In case of no augmentation is NULL (default).

Value

A vector of length n.
