1. Covariance
   In probability theory and statistics, covariance is a measure of how much two random variables change together. If the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the smaller values, i.e. the variables tend to show similar b...

3. Covariance
   A 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.

4. Covariance
   A statistical measure of the degree to which two variables (e.g., securities' returns) move together. A positive value means that, on average, they move in the same direction.

16. covariance
    The tendency of two random variables to move in tandem. This is important in applications such as survey-taking and sociology, as well as in many branches of science, because, if two things tend to vary together, there is a good chance they may be causally linked. Related entry &nbs...
