The Heston Stochastic Volatility Model: an Approximate Approach
The aim of this thesis is to find an efficient simulation method of the Heston model of stochastic volatility to price path dependent derivatives. The volatility process in this model has an exact transition density defined as a scaled non central chi2 density. By implementing classic approaches of approximating the non central chi2 distribution, and modifying Andersen's Quadratic Exponential
