rvbern {rv} | 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.
