estimation methods for copula parameters are usually motivated by density representations and decompositions for the log-likelihood of dependence mod- els as in (1) and (2). When the parameters appear linearly in these expressions then the least squares estimation problem can be solved in closed form, and it is relatively straightforward to derive the statistical properties for the resulting parameter estimates.
