similar in spirit to the concept of realized variance. We see immediately that there are many difficulties with comparing the two series. The realized variance proxy is a much more promising estimate of daily variance than the squared daily return. Permalink, join GitHub today, gitHub is home to over 28 million developers working together to host and review code, manage projects, and build software together. Additionally, other modeling periodicities could be tried to find an optimal forecasting granularity. These forecasts are compared against those generated from models fit to daily data. One of the most interesting papers, co-authored by Bollerslev himself, attempts to combat the argument that, while garch models often seem to fit well in-sample, they have poor forecasting performance, citeAndersonBollerslev. How difficult was this for you? The notation of 288(j1) is used to ensure that the correct day's worth of 5-minute variance forecasts are summed. Overall, just a standard geom_line with some color and line thickness modifications. Exercise 6, economist style economics time series.
