In this study, we predict the daily volatility of the S&P CNX NIFTY market index of India using the basic … jump and continuous component from the realized volatility. We also tried to investigate whether dividing volatility into … simple and threshold jumps and continuous variation yields a substantial improvement in volatility forecasting or not. The …
