1Blurb:: 2Parameter for the hypergeometric probability distribution describing the size of the total population 3Description:: 4 5The density function for the hypergeometric distribution is given by: 6\f[f(x) = \frac{\left(\begin{array}{c}m\\x\end{array}\right)\left(\begin{array}{c}{N-m}\\{n-x}\end{array}\right)}{\left(\begin{array}{c}N\\n\end{array}\right)}\f] 7where the three distribution parameters are: 8- <em>N is the total population</em> 9- m is the number of items in the selected population (e.g. the number of white balls in the full urn of N items) 10- n is the size of the sample drawn (e.g. number of balls drawn) 11 12In addition, 13- x, the abscissa of the density function, indicates the number of successes (e.g. drawing a white ball) 14- \f$\left(\begin{array}{c}a\\b\end{array}\right)\f$ indicates a binomial coefficient ("a choose b") 15 16Topics:: 17Examples:: 18Theory:: 19Faq:: 20See_Also:: 21
