| Abstract: | The copula functions are employed to study the entropy theory and a conception of dependence structure entropy is defined for measuring the dependence structure of random variables.The joint entropy is divided into the dependence structure entropy and the marginal entropy,which is useful of investigating the dependence structure of random variables.In addition,the invariability of dependence structure entropy of bivariate variables under monotonous transforming is discussed and extended to multivariable cas... |
