Note: each reported value is for a particular combination of moneyness and time to expiration. Three independent simulations are carried out, while 10,000 underlying price paths are generated in each simulation. The first row reports the number of put options with the corresponding combination of moneyness and time to expiration. The remaining rows show the statistic results of the MPE, RMSE, and MAPE for each combination. The total number of options analyzed is 4430, the lowest moneyness is , the highest moneyness is , and the time to expiration is in between 16 and 357 days.
