In particular, when the copula C is totally positive of order 2, we give a sufficient condition on ψ that ensures that any distortion of C by means of ψ is again a copula. The presented results allow us to introduce in a more flexible way families of copulas exhibiting different behavior in the tails. date: 2010 type: Article type: PeerReviewed format: application/pdf language: en identifier: http://eprints.imtlucca.it/709/1/Durante_Foschi_Sarkoci.pdf identifier: Durante, Fabrizio and Foschi, Rachele and Sarkoci, Peter Distorted Copulas: Constructions and Tail Dependence.
