协方差

Covariance

在概率理论和统计学中,协方差是两个随机变量共同变化的量度。 如果一个变量的较大值主要对应于另一个变量的较大值,并且对于较小的值也是相同的,即变量趋向于显示类似的行为,则协方差为正。 在相反的情况下,当一个变量的较大值主要对应于另一个变量的较小值时,即变量趋向于表现出相反的行为,协方差为负。 因此,协方差的符号显示了变量之间的线性关系的趋势。 协方差的大小不容易解释。 然而,协方差的归一化版本,相关系数通过其幅度显示线性关系的强度。 必须区分两个随机变量的协方差,这两个随机变量是可以被看作联合概率分布的属性的群体参数以及作为参数的估计值的样本协方差。 In probability theory and statistics, covariance is a measure of how much two random variables change together. If the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the smaller values, i.e., the variables tend to show similar behavior, the covariance is positive. In the opposite case, when the greater values of one variable mainly correspond to the smaller values of the other, i.e., the variables tend to show opposite behavior, the covariance is negative. The sign of the covariance therefore shows the tendency in the linear relationship between the variables. The magnitude of the covariance is not easy to interpret. The normalized version of the covariance, the correlation coefficient, however, shows by its magnitude the strength of the linear relation. A distinction must be made between the covariance of two random variables, which is a population parameter that can be seen as a property of the joint probability distribution, and the sample covariance, which serves as an estimated value of the parameter.

在英语 词典里covariance的定义

词典中协方差的定义是两个随机变量之间关联性的量度,等于偏离两个变量平均值的偏差的乘积的期望值,并且通过与样本均值的偏差的乘积之和来估计 用于两个变量的相关值除以采样点的数量。 写作Cov。

The definition of covariance in the dictionary is a measure of the association between two random variables, equal to the expected value of the product of the deviations from the mean of the two variables, and estimated by the sum of products of deviations from the sample mean for associated values of the two variables, divided by the number of sample points. Written as Cov.
