%description
Adds the MIxing-Data Sampling (MIDAS, Ghysels et al. (2007)
<doi:10.1080/07474930600972467>) components to a variety of GARCH and MEM
(Engle (2002) <doi:10.1002/jae.683>, Engle and Gallo (2006)
<doi:10.1016/j.jeconom.2005.01.018>, and Amendola et al. (2024)
<doi:10.1016/j.seps.2023.101764>) models, with the aim of predicting the
volatility with additional low-frequency (that is, MIDAS) terms. The
estimation takes place through simple functions, which provide in-sample
and (if present) and out-of-sample evaluations. 'rumidas' also offers a
summary tool, which synthesizes the main information of the estimated
model. There is also the possibility of generating one-step-ahead and
multi-step-ahead forecasts.
