CovarianceA 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(xi-m(x))(yi-m(y)), where m(·) is the mean of the values in its argument.CovarianceA 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.Covariance Similar MatchesSerial covarianceSerial covarianceThe covariance between a variable and the lagged value of the variable; the same as autocorrelation. |
