Empirical‐Process Limit Theory and Filter Approximation Bounds for Score‐Driven Time Series Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT This article examines the filtering and approximation‐theoretic properties of score‐driven time series models. Under specific Lipschitz‐type and tail conditions, new results are derived, leading to maximal and deviation inequalities for the filtering approximation error using empirical process theory.

Discrete Event Systems Theory for Fast Stochastic Simulation via Tree Expansion

Systems
Paratemporal methods based on tree expansion have proven to be effective in efficiently generating the trajectories of stochastic systems. However, combinatorial explosion of branching arising from multiple choice points presents a major hurdle that must

Eye Movements, Item Modality, and Multimodal Second Language Vocabulary Learning: Processing and Outcomes

Language Learning, EarlyView.
Abstract This study examined second language vocabulary processing and learning in reading only (RO) versus reading while listening (RWL). 119 English learners read or read‐while‐listening to a story embedded with 25 pseudowords, 10 times each, and had their eye movements tracked.

Polynomials of Binomial Type from Truncated Delta Series

European Journal of Combinatorics, 1991
The author calls a sequence of polynomials \((b_ n(x))_ {n\geq0}\) of binomial type if there exists a formal power series \(\beta (t)=\sum _ {k\geq1} ^ {}\beta _ kt^ k\) with \(\beta _ 1\neq0\) such that \[ \sum _ {n\geq0} ^ {}b_ n(x)t^ n=e^ {x\beta (t)}.

The Social Origins and Education of the British Civil Service Elite, 1945–2022

Public Administration, EarlyView.
ABSTRACT We provide a fuller account than previously available of the extent of change in the social backgrounds of the British civil service elite from 1945 onwards. We consider our findings in relation to questions of meritocracy in recruitment to the elite and of the representativeness of the elite of the population at large.

Sentiment-Driven Statistical Modelling of Stock Returns over Weekends

Computation
We propose a two-stage statistical learning framework to investigate how financial news headlines posted over weekends affect stock returns. In the first stage, Natural Language Processing (NLP) techniques are used to extract sentiment features from news

Nutrient landscape of a cricket nymph: How dietary protein and carbohydrate shape intake, performance, and body composition in the two‐spotted cricket, Gryllus bimaculatus

Physiological Entomology, EarlyView.
Survival of Gryllus bimaculatus nymphs was highest on protein‐biased diets (P:C = 3.86:1), whereas growth and body mass were maximized on slightly carbohydrate‐biased diets (P:C = 1:1.47). Maximum body protein and lipid contents were attained at P:C ratios of 1.14:1 and 1:5.56, respectively. When given a food choice, G. bimaculatus nymphs self‐selected
