Long memory persistence in the factor of Implied volatility dynamics
Härdle, Wolfgang Karl; Mungo, Julius - 2007
The volatility implied by observed market prices as a function of the strike and time to maturity form an Implied Volatility Surface (IVS). Practical applications require reducing the dimension and characterize its dynamics through a small number of factors. Such dimension reduction is...
