The probability generating function of the hypergeometric distribution is a hypergeometric series. The PGF is P (t) = \sum_ {k=0}^n f (k) t^k where f is the hypergeometric PDF, given above. Simple algebra shows that \frac {f (k+1)} {f (k)} = \frac { (r - k) (n - k)} { (k + 1) (N - r - n + k + 1)}

Exercise 3.7 (The Hypergeometric Probability Distribution) 1. Hypergeometric: televisions. Seven television (n = 7) tubes are chosen at ran-dom from a shipment of N = 240 television tubes of which r = 15 are defective. (a) The probability that y = 4 of the chosen televisions are defective is p(4) = r y N −r n− y N n

X = number of successes P(X = x) = M x L n− x N n X is said to have a hypergeometric distribution Example: Draw 6 cards from a deck without replacement. The Binomial distribution can be considered as a very good approximation of the hypergeometric distribution as long as the sample consists of 5% or less of the population. One would need a good understanding of binomial distribution in order to understand the hypergeometric distribution in a great manner. See the entry for noncentral hypergeometric distributions for an explanation of the difference between these two distributions and a discussion of which distribution to use in various situations. The two distributions are both equal to the (central) hypergeometric distribution when the odds ratio is 1. The hypergeometric distribution is used for sampling without replacement.

The density of this distribution with parameters m, n and k (named Np, N-Np, and n, respectively in the reference below, where N := m+n is also used in other references) is given by p(x) = choose(m, x) choose(n, k-x) / choose(m+n, k) for x = 0, …, k. The hypergeometric distribution can be used to determine this distribution over k. It's not straightforward why the doctor would know n and m , but not k . Perhaps n and m are dictated by the experimental design, while the experimenter is left blind to the true value of k . 6. Show that the conditional distribution of [Yi:i∈A] given {Yj=yj:j∈B} is multivariate hypergeometric with parameters r, [mi:i∈A], and z. Combinations of the basic results in Exercise 5 and Exercise 6 can be used to compute any marginal or conditional distributions of the counting variables.

x≦n The hypergeometric distribution describes the probability of choosing k objects with a certain feature in n draws without replacement, from a finite population of size N that contains K objects with that feature. how to do the calculate the hypergeometric distribution using a ti 89 or titanium(Recorded with http://screencast-o-matic.com) Hypergeometric Distribution The hypergeometric distribution is a discrete probability distribution that describes the number of successes in a sequence of n draws from a finite population without replacement.

In statistics, the hypergeometric distribution is the discrete probability distribution generated by picking colored balls at random from an urn without replacement. Various generalizations to this distribution exist for cases where the picking of colored balls is biased so that balls of one color are more likely to be picked than balls of another color. In mathematics, a generalized hypergeometric series is a power series in which the ratio of successive coefficients indexed by n is a rational function of n. The series, if convergent, defines a generalized hypergeometric function, which may then be defined over a wider domain of the argument by analytic continuation. The generalized hypergeometric series is sometimes just called the hypergeometric series, though this term also sometimes just refers to the Gaussian hypergeometric The probability generating function of the hypergeometric distribution is a hypergeometric series.

Combinations of the basic results in Exercise 5 and Exercise 6 can be used to compute any marginal or conditional distributions of the counting variables. Moments The hypergeometric distribution is an example of a discrete probability distribution because there is no possibility of partial success, that is, there can be no poker hands with 2 1/2 aces. Said another way, a discrete random variable has to be a whole, or counting, number only. Hypergeometric Experiment.
