I believe that Taleb made a mistake in his book.

The findings show that countries which are investigated have limited interaction and their volatility reveals a regional character. Comparing the Parkinson number $P$ with the definition of periodically sampled historical volatility gives this result: Such measurement cannot be used to compare close-to-close volatility with intraday high/low. I found that if I adjust the Parkinson's HL vol by 0.0025, it fits very close to the volatility suggested by the GARCH(1,1) model. As a result, I believe that the theoretical ratio of Parkinson number to close-to-close volatility should be 1, instead of 1.66( but in another situation, if the 1/4log2 was not involved in Parkinson Number Formula, namely the std var of log(H/L), the ratio should be 1.66 and I believe that Taleb mistakenly mixed them up.).

Based on various error measuring parameters, Parkinson estimator had been examined as more accurate estimator than any other estimator based on RMSE, MPE and MASE in forecasting through ARIMA Technique.

He goes on to say that if P is higher than 1.67*HV, then the trader needs to hedge a long gamma position more frequently. The model is t = t e t, where{e t} are Gaussian white noise, independent of{ t}, and t =logx t logx t1 are the "returns". where xi are the logarithmic returns calculated based on closing prices, and N is the sample size. This script calculates and analyses the following historical volatility estimators: > the Meilijson estimator (2009).
