Correlation coefficientA standardized statistical measure of the dependence of two random variables, defined as the covariance divided by the standard deviations of two variables.Correlation coefficient Similar MatchesCorrelationCorrelationStatistical measure of the degree to which the movements of two variables (stoc../../finance-glossary/optio../../finance-glossary/convertible prices or returns) are related. See: Correlation coefficient. CorrelationCorrelationA measure of the extent to which two economic or statistical variables move together, normalized so that its values range from -1 to +1. It is defined as the covariance of the two variables divided by the square root of the product of their variances. The correlation is used in trade theory to express weak relationships among economic variables. Correlation IntegralCorrelation IntegralThe probability that two points are within a certain distance from one another. Used in the calculation of the correlation dimension. AutocorrelationAutocorrelationThe correlation of a variable with itself over successive time intervals. Sometimes called serial correlation. Correlation DimensionCorrelation DimensionAn estimate of the Fractal Dimension which measures the probability that two points chosen at random will be within a certain distance of each other, and examines how this probability changes as the distance is increased. White noise will fill its space since its components are uncorrelated, and its correlation dimension is equal to whatever dimension it is placed in. A dependent system will be held together by its correlations and retain its dimension whatever embedding dimension it is placed in, as long as it is greater than its fractal dimension.
