A New Improvement Scheme for Approximation Methods of Probability Density Functions

著者:Akihiko Takahashi, Yukihiro Tsuzuki

Abstract

This paper develops a new scheme for improving an approximation method of a probability density function, which is inspired by the idea in best approximation in an inner product space. Moreover, we apply “Dykstra’s cyclic projections algorithm” for its implementation. Numerical examples for application to an asymptotic expansion method in option pricing demonstrate the effectiveness of our scheme under SABR model.
