Generalized Factorizability Of Certain Implicit Dependence Copulas, Peerapong Panyasakulwong Jan 2020

Generalized Factorizability Of Certain Implicit Dependence Copulas, Peerapong Panyasakulwong

Chulalongkorn University Theses and Dissertations (Chula ETD)

The copula CX,Y of random variables X and Y that are uniformly distributed on [0,1] is called an implicit dependence copula if f(X)=g(Y) almost surely for some Borel functions f and g on [0,1]. Via a generalized Markov product, we give a one-to-one correspondence between the implicit dependence copulas and the parametric classes of subcopulas on a corresponding domain for the cases that f=g=Λθ, the tent function whose top is at (θ,1). We also show in the case f=g=α, a simple measure-preserving function, that implicit dependence copulas are generalized factorizable.
