Randomness tests — (or tests of randomness), in data evaluation, are used to analyze the distribution pattern of a set of data. In stochastic modeling, as in some computer simulations, the expected random input data can be verified to show that tests were performed … Wikipedia

Applications of randomness — Randomness has many uses in gambling, divination, statistics, cryptography, art, etc.Note that these uses may have different requirements when it comes to statistical randomness or unpredictability, which in turn leads to different randomization… … Wikipedia
Statistical randomness — A numeric sequence is said to be statistically random when it contains no recognizable patterns or regularities; sequences such as the results of an ideal die roll, or the digits of π exhibit statistical randomness.Statistical randomness does not … Wikipedia
Ljung-Box test — In statistics, there are a large number of tests of randomness. The Ljung Box test is a type of statistical test of whether any of a group of autocorrelations of a time series are different from zero. Instead of testing randomness at each… … Wikipedia
Wald-Wolfowitz runs test — The runs test (also called Wald Wolfowitz test) is a non parametric test that checks a randomness hypothesis for a two valued data sequence. More precisely, it can be used to test the hypothesis that the elements of the sequence are mutually… … Wikipedia
Complete spatial randomness — (CSR) describes a point process whereby point events occur within a given study area in a completely random fashion. Such a process is often modeled using only one parameter, i.e. the density of points, ρ within the defined area. This is also… … Wikipedia
Runs Test — A statistical procedure that examines whether a string of data is occurring randomly given a specific distribution. The runs test analyzes the occurrence of similar events that are separated by events that are different. For example, a list of… … Investment dictionary
Algorithmically random sequence — Intuitively, an algorithmically random sequence (or random sequence) is an infinite sequence of binary digits that appears random to any algorithm. The definition applies equally well to sequences on any finite set of characters. Random sequences … Wikipedia

Diehard tests — The diehard tests are a battery of statistical tests for measuring the quality of a random number generator. They were developed by George Marsaglia over several years and first published in 1995 on a CD ROM of random numbers. These are the tests … Wikipedia
