Revisiting EWMA in High‐Frequency‐Based Portfolio Optimization: A Comparative Assessment

Journal of Applied Econometrics, EarlyView.
ABSTRACT This paper compares the statistical and economic performance of state‐of‐the‐art high‐frequency (HF) based multivariate volatility models with a simpler, widely used alternative, the Exponentially Weighted Moving Average (EWMA) filter. Using over two decades of 100 U.S.

Robust Tests of Forecast Accuracy for Factor‐Augmented Regressions With an Application to the Novel EA‐MD‐QD Dataset

Journal of Applied Econometrics, EarlyView.
ABSTRACT We present four novel tests of equal predictive accuracy and encompassing á Pitarakis (2023, 2025) for factor‐augmented regressions. Factors are estimated using cross‐section averages (CAs) of grouped series and our theoretical findings are empirically relevant: asymptotic normality, robustness to an overspecification of the number of factors,

‘Pre‐Technologies’ and the Lifeworld: Assistive Technologies as ‘Pre‐Technologies’ for Self‐Formation as Freedom

Journal of Applied Philosophy, EarlyView.
ABSTRACT This article identifies assistive technologies (ATs) as ‘pre‐technologies’ mediating access to other technologies for disabled subjects (DSs). The motivation is to show that without ATs, DSs cannot be said to have the same level of access to freedom and self‐forming activities as able‐bodied subjects.

Colourings of Uniform Group Divisible Designs and Maximum Packings

Journal of Combinatorial Designs, EarlyView.
ABSTRACT A weak c $c$‐colouring of a design is an assignment of colours to its points from a set of c $c$ available colours, such that there are no monochromatic blocks. A colouring of a design is block‐equitable, if for each block, the number of points coloured with any available pair of colours differ by at most one.

Are sensory processing difficulties in infancy predictive of child mental health at 5‐years? Findings from the Etude Longitudinale Francaise depuis l'Enfance French national birth cohort

JCPP Advances, EarlyView.
Abstract Background People with neurodevelopmental and mental health conditions have been demonstrated to have elevated rates of sensory processing (SP) difficulties in research and practice but the temporal order of this relationship is unclear. Methods This study sought to investigate whether SP difficulties in infancy predicted mental health at 5 ...

Intergenerational transmission of anxiety: A comparison of transdiagnostic and disorder‐specific pathways

JCPP Advances, EarlyView.
Abstract Background Individuals with a parental history of anxiety disorders are at risk of developing an anxiety disorder. Prior studies have focused on the transmission of specific anxiety disorders across generations (i.e., disorder‐specific transmission), often overlooking the possibility that a general tendency to develop various forms of anxiety ...
