72Pivotal quantity — In statistics, a pivotal quantity is a function of observations whose distribution does not depend on unknown parameters.More formally, given an independent and identically distributed sample X = (X 1,X 2,ldots,X n) from a distribution with… …
73Negative binomial distribution — Probability mass function The orange line represents the mean, which is equal to 10 in each of these plots; the green line shows the standard deviation. notation: parameters: r > 0 number of failures until the experiment is stopped (integer,… …
74Exponentialfamilie — In der Wahrscheinlichkeitstheorie und in der Statistik ist eine Exponentialfamilie eine Klasse von Wahrscheinlichkeitsverteilungen einer ganz bestimmten Form. Man wählt diese spezielle Form, um bestimmte Rechenvorteile auszunutzen oder aus… …
75Natural exponential family — In probability and statistics, the natural exponential family (NEF) is a class of probability distributions that is a special case of an exponential family (EF). Many common distributions are members of a natural exponential family, and the use… …
76Multivariate normal distribution — MVN redirects here. For the airport with that IATA code, see Mount Vernon Airport. Probability density function Many samples from a multivariate (bivariate) Gaussian distribution centered at (1,3) with a standard deviation of 3 in roughly the… …
77McNemar's test — In statistics, McNemar s test is a non parametric method used on nominal data. It is applied to 2 × 2 contingency tables with a dichotomous trait, with matched pairs of subjects, to determine whether the row and column marginal… …
78Basu's theorem — In statistics, Basu s theorem states that any complete sufficient statistic is independent of any ancillary statistic. This is a 1955 result of Debabrata Basu.It is often used in statistics as a tool to prove independence of two statistics, by… …
79Multinomial test — In statistics, the multinomial test is the test of the null hypothesis that the parameters of a multinomial distribution equal specified values. It is used for categorical data; see Read and Cressie[1]. We begin with a sample of N items each of… …
80Golomb coding — is a data compression scheme invented by Solomon W. Golomb in the 1960s. The scheme is based on entropy encoding and is optimal (in the sense of Shannon s source coding theorem) for alphabets following a geometric distribution, making it highly… …
