Again, as you probably already know, the main appeal of copulas is that you can essentially separate the marginals (marginal distributions) from the dependence structure and model them separately.

The theta's correspond directly the the parameters of the functions. For example, (if I have this right), the Clayton copula has the form C θ ( u, v) = max ( [ u − θ + v − θ − 1] − 1 / θ, 0). Table 2 in the paper I linked to gives Kendall's tau as τ = θ θ + 2. So if you used Kendall's tau to estimate θ in the Clayton, you ...
