切比雪夫的不平等

Chebyshev's inequality

在概率理论中,切比雪夫的不等式保证在任何概率分布中,“几乎所有”的值都接近于平均值 - 精确的语句是,不超过1 / k2的分布值可以超过距平均值的k个标准偏差 。 这个规则通常称为切比雪夫定理,统计学中关于平均值的标准偏差范围。 不等式具有很大的实用性,因为它可以应用于完全任意的分布,例如可以用来证明大量的弱定律。 在实际使用中,与适用于正态分布的经验规则相反,切比雪夫不等式下,只有75%的值必须在三个标准差范围内的平均值和89%的两个标准偏差之内。 切比雪夫这一术语的不平等也可能指马尔科夫的不平等,特别是在分析的背景下。 In probability theory, Chebyshev's inequality guarantees that in any probability distribution, "nearly all" values are close to the mean — the precise statement being that no more than 1/k2 of the distribution's values can be more than k standard deviations away from the mean. The rule is often called Chebyshev's theorem, about the range of standard deviations around the mean, in statistics. The inequality has great utility because it can be applied to completely arbitrary distributions, for example it can be used to prove the weak law of large numbers. In practical usage, in contrast to the empirical rule, which applies to normal distributions, under Chebyshev's inequality a minimum of just 75% of values must lie within two standard deviations of the mean and 89% within three standard deviations. The term Chebyshev's inequality may also refer to the Markov's inequality, especially in the context of analysis.

在英语 词典里Chebyshev's inequality的定义

切比雪夫不等式在字典中的定义是一个基本定理,即随机变量与其平均值相差超过k个标准差的概率小于或等于1 / k²。

The definition of Chebyshev's inequality in the dictionary is the fundamental theorem that the probability that a random variable differs from its mean by more than k standard deviations is less than or equal to 1/ k².
