CovarianceCovarianceA measure of the extent to which two economic or statistical variables move up and down together. For two variables x and y with values xi, yi, i=1,…,n, the covariance is cov(x,y) = Si=1…n(xim(x))(yim(y)), where m(·) is the mean of the values in its argument. CovarianceCovarianceA statistical measure of the degree to which random variables move together. A positive covariance implies that one variable is above (below) its mean value when the other variable is above (below) its mean value. Mean variance criterionMean variance criterionThe selection of portfolios based on the means and variances of their returns. The choice of the higher expected return portfolio for a given level of variance or the lower variance portfolio for a given expected return. VarianceVarianceA measure of dispersion of a set of data points around their mean value. The mathematical expectation of the average squared deviations from the mean. The square root of the variance is the standard deviation.
