function of random variable
1Random variable — A random variable is a rigorously defined mathematical entity used mainly to describe chance and probability in a mathematical way. The structure of random variables was developed and formalized to simplify the analysis of games of chance,… …
2random variable — Statistics. a quantity that takes any of a set of values with specified probabilities. Also called variate. [1935 40] * * * In statistics, a function that can take on either a finite number of values, each with an associated probability, or an… …
3Random Variable — A variable whose value is unknown or a function that assigns values to each of an experiment s outcomes. Random variables are often designated by letters and can be classified as discrete, which are variables that have specific values, or… …
4random variable — noun a) A quantity whose value is random and to which a probability distribution is assigned, such as the possible outcome of a roll of a dice. b) A measurable function from a sample space to the measurable space of possible values of the… …

7random variable — noun Date: 1937 a variable that is itself a function of the result of a statistical experiment in which each outcome has a definite probability of occurrence called also variate …
8Multivariate random variable — In mathematics, probability, and statistics, a multivariate random variable or random vector is a list of mathematical variables each of whose values is unknown, either because the value has not yet occurred or because there is imperfect… …
9Random element — The term random element was introduced by Maurice Frechet in 1948 to refer to a random variable that takes values in spaces more general than had previously been widely considered. Frechet commented that the development of probability theory and… …
10Random permutation statistics — The statistics of random permutations, such as the cycle structure of a random permutation are of fundamental importance in the analysis of algorithms, especially of sorting algorithms, which operate on random permutations. Suppose, for example,… …
