WebARCH and GARCH models have become important tools in the analysis of time series data, particularly in financial applications. These models are especially useful when the goal of the study is to analyze and forecast volatility. WebThe autoregressive conditional heteroscedasticity (ARCH) model has been widely used to model the volatility of economic and financial time series data since its introduction by Engle (1982). The ARCH model and its gener-alizations, especially the generalized ARCH (GARCH) model (Bollerslev, 1986), provide an appealing structure
A New Test for ARCH Effects and Its Finite-Sample Performance
If an autoregressive moving average (ARMA) model is assumed for the error variance, the model is a generalized autoregressive conditional heteroskedasticity (GARCH) model. In that case, the GARCH (p, q) model (where p is the order of the GARCH terms $${\displaystyle ~\sigma ^{2}}$$ and q is the order … See more In econometrics, the autoregressive conditional heteroskedasticity (ARCH) model is a statistical model for time series data that describes the variance of the current error term or innovation as a function of the actual sizes … See more In a different vein, the machine learning community has proposed the use of Gaussian process regression models to obtain a GARCH scheme. This results in a nonparametric modelling scheme, which allows for: (i) advanced robustness to overfitting, since … See more To model a time series using an ARCH process, let $${\displaystyle ~\epsilon _{t}~}$$denote the error terms (return residuals, with respect to a mean process), i.e. the series terms. These $${\displaystyle ~\epsilon _{t}~}$$ are split into a stochastic piece See more • Bollerslev, Tim; Russell, Jeffrey; Watson, Mark (May 2010). "Chapter 8: Glossary to ARCH (GARCH)" (PDF).
