A stochastic volatility Libor model and its robust calibration
2007, Belomestny, Denis, Mathew, Stanley, Schoenmakers, John G.M.
In this paper we propose a Libor model with a high-dimensional specially structured system of driving CIR volatility processes. A stable calibration procedure which takes into account a given local correlation structure is presented. The calibration algorithm is FFT based, so fast and easy to implement.
