Recurrent conditional heteroskedasticity

open access: yesJournal of Applied Econometrics, 2022
SummaryWe propose a new class of financial volatility models, called the REcurrent Conditional Heteroskedastic (RECH) models, to improve both in‐sample analysis and out‐of‐sample forecasting of the traditional conditional heteroskedastic models. In particular, we incorporate auxiliary deterministic processes, governed by recurrent neural networks, into

Generalized autoregressive conditional heteroskedasticity [PDF]

open access: yesJournal of Econometrics, 1986
Abstract A natural generalization of the ARCH (Autoregressive Conditional Heteroskedastic) process introduced in Engle (1982) to allow for past conditional variances in the current conditional variance equation is proposed. Stationarity conditions and autocorrelation structure for this new class of parametric models are derived ...

A TEST FOR CONDITIONAL HETEROSKEDASTICITY IN TIME SERIES MODELS [PDF]

open access: yesJournal of Time Series Analysis, 1992
Abstract. When testing for conditional heteroskedasticity and nonlinearity, the power of the test in general depends on the functional forms of conditional heteroskedasticity and nonlinearity that are allowed under the alternative hypothesis. We suggest a test for conditional heteroskedasticity and nonlinearity with the nonlinear autoregressive ...

Neural Generalised AutoRegressive Conditional Heteroskedasticity

open access: yesCoRR, 2022
We propose Neural GARCH, a class of methods to model conditional heteroskedasticity in financial time series. Neural GARCH is a neural network adaptation of the GARCH 1,1 model in the univariate case, and the diagonal BEKK 1,1 model in the multivariate case.

Probabilistic Forecasting of Wind Power Generation Using Online LASSO VAR and EGARCH Model

open access: yesShanghai Jiaotong Daxue xuebao, 2023
Wind power generation has uncertainty due to the high fluctuation of wind speed. In traditional wind power prediction models, the uncertainty is measured by normal distribution with zero mean and constant variance.
