Conditional Heteroscedasticity and Garch Models
a for forecasting purposes arises from the fact that this conditional mean is allowed to be a random varible which depends on the available data, and evolves with time. The conditional variance, however, is r simply var [x e x ] = var [ε ] =σ , which remains constant regardless of the given data. Thus, the linea t t −1 t ε AR (1) model fails to adequately describe the conditional variance. In p...
متن کاملMixture Gaussian Process Conditional Heteroscedasticity
Generalized autoregressive conditional heteroscedasticity (GARCH) models have long been considered as one of the most successful families of approaches for volatility modeling in financial return series. In this paper, we propose an alternative approach based on methodologies widely used in the field of statistical machine learning. Specifically, we propose a novel nonparametric Bayesian mixtur...
متن کاملGeneralized R-estimators under Conditional Heteroscedasticity
In this paper, we extend the classical idea of Rank-estimation of parameters from homoscedastic problems to heteroscedastic problems. In particular, we define a class of rank estimators of the parameters associated with the conditional mean function of an autoregressive model through a three-steps procedure and then derive their asymptotic distributions. The class of models considered includes ...

متن کاملMoment and Memory Properties of Linear Conditional Heteroscedasticity Models
This paper analyses moment and near-epoch dependence properties for the general class of models in which the conditional variance is a linear function of squared lags of the process. It is shown how the properties of these processes depend independently on the sum and rate of convergence of the lag coefficients, the former controlling the existence of moments, and the latter the memory of the v...
