21 ## Compute the probability density function (PDF) at @var{x} of the |
|
22 ## hypergeometric distribution with parameters @var{m}, @var{t}, and |
|
23 ## @var{n}. This is the probability of obtaining @var{x} marked items |
|
24 ## when randomly drawing a sample of size @var{n} without replacement |
|
25 ## from a population of total size @var{t} containing @var{m} marked items. |
|
26 ## |
|
27 ## The arguments must be of common size or scalar. |
