Detailed Description

template<class copulaPolicy>

class QuantLib::RecursiveLossModel< copulaPolicy >" Recursive STCDO default loss model for a heterogeneous pool of names. The pool names are heterogeneous in their default probabilities, notionals and recovery rates. Correlations are given by the latent model. The recursive pricing algorithm used here is described in Andersen, Sidenius and Basu; 'All your hedges in one basket', Risk, November 2003, pages 67-72

Notice that using copulas other than Gaussian it is only an
approximation (see remark on p.68).
