Backtesting portfolio value-at-risk with estimated portfolio weights

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2020; 41 (5)

This article theoretically and empirically analyzes backtesting portfolio value-at-risk (VaR) with estimation risk in an intrinsically multi-variate f......

AN ASYMPTOTIC F TEST FOR UNCORRELATEDNESS IN THE PRESENCE OF TIME SERIES DEPENDENCE

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2020; 41 (4)

We propose a simple asymptotically F-distributed Portmanteau test for zero autocorrelations in an otherwise dependent time series. By employing the or......

Two-Step Estimation for Time Varying Arch Models

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2020; 41 (4)

A time varying-40 autoregressive conditional heteroskedasticity (ARCH) model is proposed to describe the changing volatility of a financial return ser......

ON THE SENSITIVITY OF GRANGER CAUSALITY TO ERRORS-IN-VARIABLES, LINEAR TRANSFORMATIONS AND SUBSAMPLING

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2019; 40 (1)

This article studies the sensitivity of Granger causality to the addition of noise, the introduction of subsampling, and the application of causal inv......

BIAS CORRECTION ESTIMATION FOR A CONTINUOUS-TIME ASSET RETURN MODEL WITH JUMPS

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2019; 40 (1)

In this article, local linear estimators are adapted for the unknown infinitesimal coefficients associated with continuous-time asset return models wi......

ASYMPTOTIC THEORY AND UNIFIED CONFIDENCE REGION FOR AN AUTOREGRESSIVE MODEL

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2019; 40 (1)

Although some unified inferences for the coefficient in an AR(1) model have been proposed in the literature, it remains open as to how to construct a ......

A Portmanteau Test for Smooth Transition Autoregressive Models

期刊: JOURNAL OF TIME SERIES ANALYSIS, 0; ()

This article investigates a portmanteau test statistic for checking model adequacy of smooth transition autoregressive (STAR) models. The asymptotic d......

Self-Weighted Lad-Based Inference for Heavy-Tailed Continuous Threshold Autoregressive Models

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2020; 41 (1)

This note investigates the self-weighted least absolute deviation estimation (SLADE) of a heavy-tailed continuous threshold autoregressive (TAR) model......

Disrupted brain functional networks in drug-naive children with attention deficit hyperactivity disorder assessed using graph theory analysis

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2019; 40 (6)

Neuroimaging studies have revealed functional brain network abnormalities in attention deficit hyperactivity disorder (ADHD), but the results have bee......

Reduced resting-state functional connectivity and sleep impairment in abstinent male alcohol-dependent patients

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2019; 40 (6)

Alcohol dependence is associated with poor sleep quality, which has both been implicated with thalamocortical circuits function. To identify the possi......

Effects of hypogonadism on brain development during adolescence in girls with Turner syndrome

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2019; 40 (6)

Gonadal steroids play an important role in brain development, particularly during puberty. Girls with Turner syndrome (TS), a genetic disorder charact......

Stress and the brain: Perceived stress mediates the impact of the superior frontal gyrus spontaneous activity on depressive symptoms in late adolescence

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2019; 40 (6)

Identifying factors for the prediction of depression is a long-standing research topic in psychiatry and psychology. Perceived stress, which reflects ......

The Marginal Density of a TMA(1) Process

期刊: JOURNAL OF TIME SERIES ANALYSIS, 0; ()

This note reconsiders the marginal density of a threshold moving average process and proposes a simple yet effective numerical algorithm to implement ......

Volatility Estimation and Jump Testing via Realized Information Variation

期刊: JOURNAL OF TIME SERIES ANALYSIS, 2019; 40 (5)

We put forward a new method to construct jump-robust estimators of integrated volatility, namely realized information variation (RIV) and realized inf......
