Dear Caleb Danquah,

The simulations are performed to graphically illustrate the quality of the estimators introduced by the copula theory. We can also show through the simulation certain performances such as robustness and evalution the quality of model..

I think Mohamed provide good references

Dear Caleb Danquah ,

There may be different purpose to simulate from copula models, however, one of them is to evaluate the performance of copula models. For instance, to choose a copula model from different copula models for further analysis. You can see my paper on copula modelling on the link below:

Wish you all the best.

With best regards,
