WitrynaFirst and Second Order Statistics. The first order statistic is the smallest sample value (i.e. the minimum), once the values have been placed in order. For example, in the … In statistics, the kth order statistic of a statistical sample is equal to its kth-smallest value. Together with rank statistics, order statistics are among the most fundamental tools in non-parametric statistics and inference. Important special cases of the order statistics are the minimum and maximum value … Zobacz więcej For example, suppose that four numbers are observed or recorded, resulting in a sample of size 4. If the sample values are 6, 9, 3, 8, the order statistics would be denoted Zobacz więcej Given any random variables X1, X2..., Xn, the order statistics X(1), X(2), ..., X(n) are also random variables, defined by sorting the values ( Zobacz więcej Moments of the distribution for the first order statistic can be used to develop a non-parametric density estimator. Suppose, we want to estimate the density $${\displaystyle f_{X}}$$ at the point $${\displaystyle x^{*}}$$. Consider the random variables Zobacz więcej • Order statistics at PlanetMath.
