Grzelak, L.A. (author), Witteveen, J.A.S. (author), Oosterlee, C.W. (author), Suárez-Taboada, M. (author)In this article, we propose an efficient approach for inverting computationally expensive cumulative distribution functions. A collocation method, called the Stochastic Collocation Monte Carlo sampler (SCMC sampler), within a polynomial chaos expansion framework, allows us the generation of any number of Monte Carlo samples based on only a...journal article 2018

van der Stoep, A.W. (author), Grzelak, L.A. (author), Oosterlee, C.W. (author)We present in a Monte Carlo simulation framework, a novel approach for the evaluation of hybrid local volatility [Risk, 1994, 7, 18–20], [Int. J. Theor. Appl. Finance, 1998, 1, 61–110] models. In particular, we consider the stochastic local volatility model—see e.g. Lipton et al. [Quant. Finance, 2014, 14, 1899–1922], Piterbarg [Risk, 2007,...journal article 2017

De Groot, M.R. (author)This thesis is about pricing swaptions under the SABR model or a variant thereof. In the interest market a stochastic local volatility is often used by practitioners to describe the volatility curve in the strike dimension of swaptions. It is a fast approach to inter- and extrapolate market quotes. It is however well-known that this approach is...master thesis 2015
