Fast calibration of the Libor Market Model with Stochastic Volatility and Displaced Diffusion
12 June 2017 - by Pierre-Edouard Arrouy, Paul Bonnefoy, Alexandre Boumezoued
As it is now crucial to get fast calibration procedures for a certain model, Milliman developed an advanced parameter inference strategy allowing to set such interest rate models in a significantly faster way compared to the classical methods available today.
