Web4 Jun 2024 · The empirical results indicate that the model improves on the benchmark Heston model by 24% in-sample and 23% out-of-sample, and better fit results from improvements in the modeling of the term structure dimension as well as the moneyness dimension. Expand WebBesides providing more flexible modeling of the time variation in the smirk, the model also provides more flexible modeling of the volatility term structure.
