rbs1 {bs}R Documentation

Random number generator from BSD (G1)

Description

Generate random numbers from the BSD with shape parameter alpha and scale parameter beta. rbs1() is based on the relationship between the standard normal distribution and the BSD; see Chang and Tang (1994).

Usage

rbs1(n, alpha = 1, beta = 1)

Arguments

n Number of observations.
alpha Shape parameter.
beta Scale parameter.

Value

rbs1() gives a vector of n random numbers from the BSD for alpha and beta.
