hypergeometric
The Hypergeometric distribution is a discrete distribution bounded by
[0,s]. It describes the number of defects, x, in a sample of size s
from a population of size N which has m total defects. The ratio of m/N
= p is sometimes used rather than m to describe the probability of a
defect. Note that defects may be interpreted as successes, in which
case x is the number of failures until (sx) successes. The sample is
taken without replacement.
The Hypergeometric distribution is used to describe sampling from a
population where an estimate of the total number of defects is desired.
It has also been used to estimate the total population of species from
a tagged subset. However, estimates of all three parameters from a data
set are notoriously fickle and error prone, so use of these parameters
to estimate a physical quantity without specifying at least one of the
parameters is not recommended.
