rVIB {FlexReg}

Random generation from the variance-inflated beta distribution

Description

The function generates random values from the variance-inflated beta distribution, or from the augmented variance-inflated beta distribution.

Usage

rVIB(n, mu, phi, p, k, 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.

p

the mixing weight. It must lie in (0, 1).

k

the extent of the variance inflation. It must lie in (0, 1).

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.
