First mean should be calculated by adding sum of each elements of the matrix. After calculating mean, it should be subtracted from each element of the matrix.Then square each term and find out the variance by dividing sum with total elements. Deviation: It is the square root of the variance.

During the late 1980s, JP Morgan developed a firm-wide VaR system. This modeled several hundred key factors. A covariance matrix was updated quarterly from 2019-10-27 var svar— Structural vector autoregressive models 5 bcns(matrix bcns) specifies a matrix that defines a set of exclusion or cross-parameter equality constraints on B. This matrix must be square with dimension equal to the number of equations in the underlying VAR. Each element of this matrix must be missing, 0, or a positive integer.
