ABSTRACT This article derives a new coefficient of relationship of two symmetric alpha-stable variables when alpha is in the interval (1,2] based on covariation. Its numerical value ranges from −1 to +1. Simulation studies are used to evaluate the performance of the coefficient of relationship estimators.
