MODEL SELECTION CRITERIA AND QUADRATIC DISCRIMINATION IN ARMA AND SETAR TIME SERIES MODELS [PDF]

open access: yes
We show that analyzing model selection in ARMA time series models as a quadratic discrimination problem provides a unifying approach for deriving model selection criteria.

Multistep Predictions from Multivariate ARMA-GARCH Models and their Value for Portfolio Management [PDF]

open access: yes, 2002
In this paper we derive the closed form solution for multistep predictions of the conditional means and their covariances from multivariate ARMA-GARCH models. These are useful e.g.

An optimal prediction in general ARMA models

open access: yes, 1990
This paper introduces a concept of a general ARMA model. The Wold's decomposition is extended to a class of stochastic processes without moment conditions.

Comparative Radiopacity of Additively Manufactured Permanent and Temporary Resins and Conventional Resin‐Based Composites

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study aimed to evaluate whether radiopacity differs among additively manufactured permanent resins, temporary resins, and conventional resin‐based composites at clinically relevant thicknesses. Materials and Methods Eight dental materials were evaluated and categorized into four groups: additively manufactured permanent resins ...

Selection of the Informative Base in ARMA-GARCH Models [PDF]

open access: yes
In this paper we consider the selection of the information set in ARMA-GARCH models using the methodology proposed in Muñoz et al. (2001) based on ideas of Phillips (1996). To that end, we analyse the performance of some selection criteria asymptotically

An improved hybrid of nonlinear autoregressive with exogenous input and autoregressive moving average for long-term machine state forecasting based on vibration signal

open access: yes, 2010
This paper presents an improvement of hybrid of nonlinear autoregressive with exogenous input (NARX) and autoregressive moving average (ARMA) for long-term machine state forecasting based on vibration data.

Attitudes Towards Sexuality and Sexual Orientation in People With Intellectual Disabilities: A Systematic Review

open access: yesJournal of Intellectual Disability Research, EarlyView.
ABSTRACT Over time, sexuality has become a crucial aspect in people's lives, regardless of physical, intellectual or social conditions, ranging from sex and sexually transmitted diseases to gender identity and sexual orientation. The aim of this study was to carry out a review of the scientific literature on sexual orientation in people with ...

On Adaptive Estimation in Nonstationary ARMA Models with GARCH Errors, [PDF]

open access: yes
This paper considers adaptive estimation in nonstationary autoregressive moving average models with the noise sequence satisfying a generalised autoregressive conditional heteroscedastic process.

Another Look at the (Ir)Relevance of Long‐Run Risks for Equity Risk Premia

open access: yesJournal of Money, Credit and Banking, EarlyView.
Abstract I investigate the empirical asset pricing implications of a three‐factor macro model that extends the baseline consumption model Consumption Capital Asset Pricing Model (CCAPM) by adding the innovations in expected long‐run consumption growth (consumption growth news) and expected long‐run consumption variance (variance news) as risk factors ...
