rFBB: Random generator from the flexible beta-binomial distribution

In FlexReg: Regression Models for Bounded Continuous and Discrete Responses

Random generator from the flexible beta-binomial distribution

Description

The function generates random values from the flexible beta-binomial distribution.

Usage

rFBB(n, size = NULL, mu, theta = NULL, phi = NULL, p, w)

Arguments

n	the number of values to generate. If length(n) > 1, the length is taken to be the number required.
size	the total number of trials.
mu	the mean parameter. It must lie in (0, 1).
theta	the overdispersion parameter. It must lie in (0, 1).
phi	the precision parameter, an alternative way to specify the overdispersion parameter theta. It must be a real positive value.
p	the mixing weight. It must lie in (0, 1).
w	the normalized distance among clusters. It must lie in (0, 1).

Value

A vector of length n.
