Build a stochastic volatility model for the daily log return of Cisco Systems stock from January 1991 to December 1999. You may download the data from the CRSP database or the file d-csco9199.txt.
Use the model to obtain a predictive distribution for 1-step ahead volatility forecast at the forecast origin December 1999.
