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

open access: yesJournal 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,

Colourings of Uniform Group Divisible Designs and Maximum Packings

open access: yesJournal 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.

Cyclothymic‐hypersensitive temperament in early adolescence: Longitudinal measurement invariance and associations with psychopathology over time

open access: yesJCPP Advances, EarlyView.
Abstract Background Cyclothymic‐Hypersensitive Temperament (CHT) is characterised by mood instability, interpersonal hypersensitivity, and emotional hyperreactivity, traits frequently observed in general population as well as clinical settings but often eluding strict diagnostic classifications.

Maternal depression across childhood and offspring young adult depression and anxiety: Testing adolescent emotion dynamics as transdiagnostic mechanisms

open access: yesJCPP Advances, EarlyView.
Abstract Background Early exposure to maternal depression can increase risk for offspring mental health problems across the lifespan. Less is known about the transdiagnostic pathways through which maternal depression influences offspring mental health risk in young adulthood.

A Coarse Geometric Approach to Graph Layout Problems

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...

Uniform asymptotic expansions for the zeros of Bessel functions

open access: yes
Reformulated uniform asymptotic expansions are derived for ordinary differential equations having a large parameter and a simple turning point. These involve Airy functions, but not their derivatives, unlike traditional asymptotic expansions. From these,
