Research of the Character on Two-dimensional Random Variables
Tian Ping · 2010
In this paper,the conception of concordance functions was given based on the discussion about description and depiction of Increasing speed of two-dimensional random variable,and the research about the concordance relation between two-dimensional random variable have one step closer for the definition of concordance metrics on two-dimensional random variable have been improved by concordance functions.Lastly the formulas and character of concordance functions were gotten as well base on copula function help and the conclusion and character of concordance functions based on its figure have been tested through some examples' specific application.
