“…To overcome the drawback of GARCH-class models, Engle, Ghysels, and Sohn, (2013) input realized volatility (RV) and the economic fundamentals into the GARCH model, forming the GARCH-MIDAS model, which prove macroeconomic fundamentals play a significant role in forecasting. In recent years, increasing numbers of researchers have used this model or modified it to analyze and forecast asset price volatility (Deng, Girardin, & Joyeux, 2018;Kang, McIver, & Yoon, 2017;Mo, Gupta, Li, & Singh, 2018;Pan et al, 2017;Wei, Liu, Lai, & Hu, 2017). Wei et al, (2017) use the GARCH-MIDAS model and dynamic model averaging combination method to forecast oil price volatility.…”
