To introduce, mathematically evaluate, and derive the asymptotic distribution for a correlation coefficient designed specifically for circular or angular data.
Formulated a specialized association coefficient to measure dependence between angular variables.
Derived the large-sample asymptotic distribution and established theoretical mathematical properties of the coefficient.
Compared the statistic against alternative circular association metrics using illustrative data examples.
Defined the statistical framework and sampling distribution for assessing correlation among circular variables.
Demonstrated through comparative examples that the proposed coefficient provides a reliable and valid measure of association for angular data relative to existing methods.
