rvbern | R Documentation |
rvbern
generates a random vector where each simulation comes from a
Bernoulli sampling distribution.
rvbern(n = 1, prob, logical = FALSE)
n |
number of random scalars to draw |
prob |
probability of "success"; may be a random vector itself |
logical |
logical; return a logical random variable instead |
rvbern
is a special case of rvbinom
with the argument size=1.
If logical
is TRUE
, the function returns a logical random
variable which has TRUE for 1, FALSE for 0. (The printed summary of this
object is slightly different from a regular continuous numeric random
variable.)
A random vector (an rv object) of length n
.
The resulting vector will not be independent and identically
distributed Bernoulli unless prob
is a fixed number.
