Writing HAR-RV-CJ Model?
I am trying to write a loop to forecast realized volatility over successive
days for the purpose of VaR prediction using the HAR-RV-CJ model which is as
follows:
log(RV_t+1) = ?_0 + ?_CD log(CV_t) + ?_CW log(CV_t-5) + ?_CM
log(CV_t-22) + ?_JD log(J_t) + ?_JW J_t-5 + ?_JM J_t-22 + e_t
where RV is realized volatility, CV is continuous volatility and J is the
jump which is RV - CV, _t is subscript for time t, which is one day
basically I know how to compute ex post CV and J, and RV and have...
