It is emphasis on contravariance rule, covariance rule and closed-behavior rule that generic-special relation must abide in this paper.
本文重点研究了建立一般-特殊关系所必须服从的抗变性、协变形原则和闭合行为原则。
The covariance between two variables can help determine the relationship between them.
两个变量之间的协方差可以帮助确定它们之间的关系。
In statistics, covariance measures how two variables change together.
在统计学中，协方差衡量两个变量如何一起变化。
Positive covariance indicates that the variables tend to move in the same direction.
正协方差表明变量倾向于朝着相同的方向移动。
Negative covariance suggests that the variables move in opposite directions.
负协方差表明变量朝着相反的方向移动。
Covariance is used in portfolio theory to measure the relationship between asset returns.
协方差在投资组合理论中用于衡量资产回报之间的关系。
The covariance matrix summarizes the variances and covariances of multiple variables.
协方差矩阵总结了多个变量的方差和协方差。
Covariance is an important concept in multivariate analysis and machine learning.
协方差是多元分析和机器学习中的重要概念。
Researchers often analyze covariance to understand the dependency between different factors.
研究人员经常分析协方差以了解不同因素之间的依赖关系。
Covariance plays a crucial role in financial modeling and risk management.
协方差在金融建模和风险管理中发挥着至关重要的作用。
Understanding covariance can help in predicting future trends and making informed decisions.
了解协方差可以帮助预测未来趋势并做出明智的决策。
We have the covariance of these two random variables.
我们有这两个随机变量的协方差。
来源: Khan Academy: Statistics (Video Version)And then we do the covariance between the vertical movements of wind and the concentration of gas.
然后我们计算风的垂直运动和气体浓度之间的协方差。
来源: Science Quickly, from Scientific AmericanIt's called an eddy covariance tower.
它被称为涡流协方差塔。
来源: Science Quickly, from Scientific AmericanNow we don't know the entire covariance, we only have one sample here of this random variable.
现在我们不知道整个协方差，我们这里只有这个随机变量的一个样本。
来源: Khan Academy: Statistics (Video Version)Well, you could view this as the covariance of X with X. But we've actually already seen this.
好吧，您可以将其视为 X 与 X 的协方差。 但实际上我们已经看到了这一点。
来源: Khan Academy: Statistics (Video Version)The covariance of a random variable with itself is really just the variance of that random variable.
随机变量与其自身的协方差实际上只是该随机变量的方差。
来源: Khan Academy: Statistics (Video Version)And the degree to which they do it together will tell you the magnitude of the covariance.
他们一起做的程度会告诉你协方差的大小。
来源: Khan Academy: Statistics (Video Version)Hopefully that gives you a little bit of intuition about what the covariance is trying to tell us.
希望这能让您对协方差试图告诉我们的内容有一点直觉。
来源: Khan Academy: Statistics (Video Version)I want to connect to this definition of covariance to everything we've been doing with least squared regression.
我想将协方差的这个定义与我们用最小二乘回归所做的一切联系起来。
来源: Khan Academy: Statistics (Video Version)So this whole video, I'm just going to rewrite this definition of covariance right over here.
所以在整个视频中，我将在这里重写协方差的定义。
