### Different Correlation Structures in CopulasData Science

Clayton copula. In the Clayton copula there is more dependence in the negative tail than in the positive tails. Hence this is useful to model variables that become more correlated in a stress scenario. For example in finance one could observe more dependence in negative stock prices returns of two assets.
