Score Permutation Based Finite Sample Inference for Generalized AutoRegressive Conditional Heteroskedasticity (GARCH) Models [PDF]

open access: greenProceedings of Machine Learning Research, Volume 51, 2016, pp. 296-304, 2018
A standard model of (conditional) heteroscedasticity, i.e., the phenomenon that the variance of a process changes over time, is the Generalized AutoRegressive Conditional Heteroskedasticity (GARCH) model, which is especially important for economics and finance.

Spatial extension of generalized autoregressive conditional heteroskedasticity models [PDF]

open access: greenSpatial Economic Analysis, 2020
This paper proposes an extension of generalized autoregressive conditional heteroskedasticity (GARCH) models for a time series to those for spatial data, which are called here spatial GARCH (S-GARCH) models. S-GARCH models are re-expressed as spatial autoregressive moving-average (SARMA) models and a two-step procedure based on quasi-likelihood ...

Forecasting the Volatilities of Philippine Stock Exchange Composite Index Using the Generalized Autoregressive Conditional Heteroskedasticity Modeling [PDF]

open access: greenInternational Journal of Statistics and Economics, 19(3), 2018, 2019
This study was conducted to find an appropriate statistical model to forecast the volatilities of PSEi using the model Generalized Autoregressive Conditional Heteroskedasticity (GARCH). Using the R software, the log returns of PSEi is modeled using various ARIMA models and with the presence of heteroskedasticity, the log returns was modeled using GARCH.

Maximum likelihood estimation of a noninvertible ARMA model with autoregressive conditional heteroskedasticity [PDF]

open access: bronzeJournal of Multivariate Analysis, 2012
We consider maximum likelihood estimation of a particular noninvertible ARMA model with autoregressive conditionally heteroskedastic (ARCH) errors. The model can be seen as an extension to the so-called all-pass models in that it allows for autocorrelation and for more flexible forms of conditional heteroskedasticity.

Bootstrapping Autoregressions with Conditional Heteroskedasticity of Unknown Form [PDF]

open access: yesSSRN Electronic Journal, 2002
Conditional heteroskedasticity is an important feature of many macroeconomic and financial time series. Standard residual-based bootstrap procedures for dynamic regression models treat the regression error as i.i.d. These procedures are invalid in the presence of conditional heteroskedasticity.

Periodic Autoregressive Conditional Heteroscedasticity [PDF]

open access: yesJournal of Business & Economic Statistics, 1996
Most high-frequency asset returns exhibit seasonal volatility patterns. This article proposes a new class of models featuring periodicity in conditional heteroscedasticity explicitly designed to capture the repetitive seasonal time variation in the second-order moments. This new class of periodic autoregressive conditional heteroscedasticity, or P-ARCH,

Adaptive inference for a semiparametric generalized autoregressive conditional heteroskedasticity model [PDF]

open access: yesJournal of Econometrics, 2021
This paper considers a semiparametric generalized autoregressive conditional heteroskedasticity (S-GARCH) model. For this model, we first estimate the time-varying long run component for unconditional variance by the kernel estimator, and then estimate the non-time-varying parameters in GARCH-type short run component by the quasi maximum likelihood ...

Long‐run predictability tests are even worse than you thought

open access: yesJournal of Applied Econometrics, Volume 37, Issue 7, Page 1334-1355, November/December 2022., 2022
Summary We derive asymptotic results for the long‐horizon ordinary least squares (OLS) estimator and corresponding t$$ t $$‐statistic for stationary autoregressive predictors. The t$$ t $$‐statistic—formed using the correct asymptotic variance—together with standard‐normal critical values result in a correctly‐sized test for exogenous predictors.

Functional generalized autoregressive conditional heteroskedasticity [PDF]

open access: greenarXiv, 2015
Heteroskedasticity is a common feature of financial time series and is commonly addressed in the model building process through the use of ARCH and GARCH processes. More recently multivariate variants of these processes have been in the focus of research with attention given to methods seeking an efficient and economic estimation of a large number of ...
