From Nominalisation to Passive in Old Tibetan: Reconstructing Grammatical Meaning in an Extinct Language1

Transactions of the Philological Society, EarlyView.
Abstract Based on an analysis of the Old Literary Tibetan corpus—a corpus of the oldest documented Tibetic language—the present study provides evidence that literary Tibetan v3 verb stems (commonly termed ‘future’) initially encoded passive voice. New arguments put forward in this article range from Trans‐Himalayan nominal morphology to early Tibetan ...

Modeling Dependence with C- and D-Vine Copulas: The R Package CDVine

Journal of Statistical Software, 2013
Flexible multivariate distributions are needed in many areas. The popular multivariate Gaussian distribution is however very restrictive and cannot account for features like asymmetry and heavy tails.

New Bivariate Copulas via Lomax Distribution Generated Distortions

AppliedMath
We develop a framework for creating distortion functions that are used to construct new bivariate copulas. It is achieved by transforming non-negative random variables with Lomax-related distributions.

Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders

Integrative Zoology, EarlyView.
Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Spatial Tail Dependence and Survival Stability in a Class of Archimedean Copulas

International Journal of Mathematics and Mathematical Sciences, 2016
This paper investigates properties of extensions of tail dependence of Archimax copulas to high dimensional analysis in a spatialized framework. Specifically, we propose a characterization of bivariate margins of spatial Archimax processes while spatial ...

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

Acta Ophthalmologica, EarlyView.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

WORLD FINANCIAL RELATIONS: UNDERSTANDING THE CREDIT DERIVATIVE SWAPS (CDS) DEPENDENCE STRUCTURE

REAd
This study investigates the copula model that best fit to model the dependence structure of Credit Derivative Swaps (CDS) spreads. For the analysis, we consider daily data from the period of January 1, 2009 to December 31, 2014.

Intermediate clinical endpoints as surrogates for overall survival after salvage prostatectomy

BJU International, EarlyView.
Objectives To evaluate biochemical recurrence‐free survival (BRFS) and metastasis‐free survival (MFS) as potential intermediate clinical endpoints (ICEs) for overall survival (OS) in patients undergoing salvage radical prostatectomy (sRP). Patients and Methods Evaluable patients were selected from a retrospective dataset, resulting in a cohort of 879 ...

LLM‐based prior elicitation for Bayesian graphical modeling

British Journal of Mathematical and Statistical Psychology, EarlyView.
ABSTRACT In the Bayesian graphical modeling framework, priors on network structure encode theoretical assumptions and uncertainty about the topology of psychological constructs under study. For instance, the Bernoulli prior specifies the probability of each pairwise interaction, the Beta–Bernoulli prior governs expected network density, and the ...

Oral Semaglutide 25 mg Versus Orforglipron 36 mg in Obesity: A Population‐Adjusted Indirect Treatment Comparison

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims This study aimed to indirectly compare the effects of oral semaglutide 25 mg versus orforglipron 36 mg on body weight loss, other cardiometabolic biomarkers, and tolerability in adults with overweight (body mass index [BMI] ≥ 27 kg/m2 and at least one obesity‐related complication) or obesity (BMI ≥ 30 kg/m2), without diabetes, using data ...
