SOME EXTENSION ON THE D-CORRELATION COEFFICIENT

In his paper1,Yaoting Zhang has given a definition of correlation measures on discrete random variables（D-correlation coefficient）by using the properties of the diversity index.In this paper,we give some extension of the D-correlation coefficient for the nondiscrete random variables by using the method of information theory.These new correlation coefficients give a better understanding of the correlation characteristics for the general random variables（or random processes）.
