This indicates that COV(X,Y)=COV(Y,X), COV(X,Z)=COV(Z,X), and COV(Y,Z)=COV(Z,Y). The covariance matrix is symmetric concerning diagonal. The diagonal values of the matrix represent the variances of X, Y, and Z variables (i.e., COV(X, X), COV(Y, Y), and COV (Z, Z)). To create the 3×3 square covariance matrix, we need to have three-dimensional data. The three-dimensional covariance matrix is shown as: The covariance matrix is represented in the following format. A negative value indicates that if one variable decreases, the other increases, and an inverse relationship exist between them. A positive value indicates that two variables will decrease or increase in the same direction.

The covariance will have both positive and negative values. It is easy and useful to show the covariance between two or more variables.

The covariance matrix is a square matrix to understand the relationships presented between the different variables in a dataset. The following formula is used for covariance determination.

Excel presented an inbuilt “Data Analysis” tool to determine the covariance between the data sets. read more among the columns and variance in columns. when the returns of one asset goes up, the return of second assets also goes up and vice versa for negative covariance. If it gives a positive number then the assets are said to have positive covariance i.e. The covariance matrix is a square matrix to show the covariance Covariance Covariance is a statistical measure used to find the relationship between two assets and is calculated as the standard deviation of the return of the two assets multiplied by its correlation.
