Case 2 – Covariance for Multiple Variables+ The variance value between Math and Science is 45.85185. The variance value between Math and History is -27.3703. The variance value between Science and History is 86.66667. Positive Covariance The presence of positive covariance indicates that the two v...

(CAPM), which is used to calculate the expected return of an asset, the covariance between a security and the market is used in the formula for one of the model’s key variables,beta. In the CAPM, beta measures the volatility, or systematic risk, of a security compared to the market ...
Second, we call that theinput-dataisindependentwhereas theoutputisdependent. Oftentimes theinput-datais consists of multiple variables, and you may ask "should the input-data independent or dependent". Well, it depends! The input-data has some relation between each other, i.e. They "co-vary"...
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 asCov(X, ...

N-way ANOVA can also be used when factors are nested, or when some factors are to be treated as continuous variables. Multiple Comparisons Multiple comparison procedures can accurately determine the significance of differences between multiple group means. ...
Gaussian process analysis of processes with multiple outputs is limited by the fact that far fewer good classes of co-variance functions exist compared with the scalar (single-output) case. To address this difficulty, we turn to covariance function models that take a form consistent in some sense...
By using least double multiplication,the author gives the origin of two definitions of covariance and correlation coefficient,and gives the reason why people usually use correlation coefficient instead of covariance to estimate the correlation degree of the two aleatory variables.This article explains thei...
Covariance: In the off-diagonal elements, the matrix represents the covariance between two variables. Covariance indicates whether two variables tend to move together or in opposite directions.Calculation:Sample Covariance: This is used to estimate population covariance based on a sample of data.
