Detailed Description

template<class RNG = PseudoRandom, class S = Statistics>
class QuantLib::MCVarianceSwapEngine< RNG, S >

Variance-swap pricing engine using Monte Carlo simulation,.

as described in Demeterfi, Derman, Kamal & Zou, "A Guide to Volatility and Variance Swaps", 1999

Tests:

returned fair variances checked for consistency with implied volatility curve.
