Hi, all
I have been reading about copula, but still very confused.
What exactly is a copula? My understanding is: there are couple of components
1. uniform cdf marginal
2. a covariance matrix
What exactly is this thing? Why am I calculating the marginals and what does it have to do with the covariance matrix?
I am reading on the bivariate Gaussian copulas and t-copulas.
