A new method to retrieve the risk-neutral probability measure from observed option prices is developed and a closed … financial returns. The expansion coefficients can be calibrated from observed option prices and can also be computed, for … the properties of the new option pricing model by calibrating it to both real-world and simulated option prices and find …
