WebWe study the impact of large cross-sections of contemporaneous aggregation of GARCH processes and of dynamic GARCH factor models. The results crucially depend on the shape of the cross-sectional distribution of the GARCH coefficients and on the cross-sectional dependence properties of the rescaled innovation. The aggregate maintains the core … Web5 aug. 2016 · Least squares (LS) requires the data to be observable. Volatility (the dependent variable of GARCH models) is latent; therefore, LS cannot be applied directly. …

Web24 mrt. 2015 · Suppose the conditional mean of returns is constant. A GARCH model gives you a fitted value of the conditional variance for each data point. These fitted values can be used to weight the data points to construct an efficient estimate of the mean (e.g. using weighted least squares); data points with high fitted conditional variance would be down … Web19 feb. 2024 · Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world.

Web28 mrt. 2024 · 2.1 GARCH Model To evaluate the performance of the LSTM model, we have developed one autoregressive model (GARCH) as benchmark models.
