udgeom | R Documentation |
Create UNU.RAN object for a Geometric distribution
with parameter prob
.
[Distribution] – Geometric.
udgeom(prob, lb = 0, ub = Inf)
prob |
probability of success in each trial. |
lb |
lower bound of (truncated) distribution. |
ub |
upper bound of (truncated) distribution. |
The Geometric distribution with prob
= p has density
p(x) = p (1-p)^x
for x = 0, 1, 2, …, 0 < p ≤ 1.
The domain of the distribution can be truncated to the
interval (lb
,ub
).
