rvbinom {rv}R Documentation

Generate Random Variables from a Binomial Sampling Model

Description

Generates a random vector from a binomial sampling model.

Usage

  rvbinom(n=1, size, prob)

Arguments

n integer, number of random variables to generate
size integer or integer-valued rv: the number of trials (size of each sample)
prob prior probability of success of each trial (may be constant or an rv object)

Details

rvbinom generates a random vector with given length, the distribution for size and the distribution for the probability of success.

Examples

  s <- 1+rvpois(1,lambda=3)        # A prior distribution on the 'size' parameter.
  rvbinom(1, size=s, prob=0.5)     # The 'size' is random.
  p <- rvbinom(1, 10, prob=0.5)/10 # Prior probability of success.
  rvbinom(1, size=10, prob=p)      # Now the probability is random.
  rvbinom(1, size=s, prob=p)       # Both the size and the probability are random.
