A Robust Spherical Correlation Coefficient Against Scale.
Abstract
There are several bi-directional situations where it is required to obtain a measure of correlation. The question has been raised often that the bi-directional correlation coefficients so far known are not scale invariant even asymptotically. Following Cox,s procedure (Cox, 1975, J. Roy. Statist. Soc. B, 380-381), a new correlation coefficient is introduced which has the desirable property of being invariant under scale for large samples with von Mises marginals. Its asymptotic distribution under the hypothesis of independence is obtained and examined.
