.liouv.iTau_s

The moment estimates are based on inversion of the formula Kendall's \(\tau\) for Clayton or Gumbel Liouville copula

Collections of functions allowing random number generations and
estimation of 'Liouville' copulas, as described in Belzile and Neslehova (2017) <doi:10.1016/j.jmva.2017.05.008>.
