The Geometric distribution is a discrete distribution bounded at 0 and
unbounded on the high side. It is a special case of the Negative
Binomial distribution. In particular, it is the direct discrete analog
for the continuous Exponential distribution. The Geometric distribution
has no history dependence, its probability at any value being
independent of a shift along the axis.
The Geometric distribution has been used for inventory demand,
marketing survey returns, a ticket control problem, and meteorological
models.
