Algebraic formula for the variance for the "n" by "m" cross-covariance matrix "between" two random vectors of length "n" and "m": where expectations are taken element-wise and formula_8 and formula_9 are random vectors of respective lengths "n" and "m". Note that this formula suffers from the same loss of significance as the formula for variance if used for calculating estimates of the covariance, and alternative algorithms should be used instead. Algebraic formula for the variance In probability theory and statistics, there are several algebraic formulae for the variance available for deriving the variance of a random variable. The usefulness of these depends on what is
