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 ...

Convergence of Archimedean Copulas [PDF]
Convergence of a sequence of bivariate Archimedean copulas to another Archimedean copula or to the comonotone copula is shown to be equivalent with convergence of the corresponding sequence of Kendall distribution functions.No extra differentiability ...

Creativity and Innovation Management, EarlyView.ABSTRACT While the literature on employees' innovative work behavior (IWB) treats leaders as a homogeneous source of firm‐internal knowledge, we examine how learning from different types of senior leaders (supervisors, coaches, and mentors) differentially affects employees' IWB and how these effects vary with the uncertainty of work tasks.

Efficient estimation of parameters in marginals in semiparametric multivariate models [PDF]
Recent literature on semiparametric copula models focused on the situation when the marginals are specified nonparametrically and the copula function is given a parametric form.

Speculative Unity in Hegel's Restrictive Identity Claim
European Journal of Philosophy, EarlyView.Abstract Hegel identifies thought with the ‘in itself’ of things. It is common to read the statement as an unrestricted claim regarding Hegel's metaphysical view of reality. I argue it should be read as the expression of what speculative truth achieves.

Pricing bivariate option under GARCH-GH model with dynamic copula: application for Chinese market [PDF]
This paper develops the method for pricing bivariate contingent claims under General Autoregressive Conditionally Heteroskedastic (GARCH) process. In order to provide a general framework being able to accommodate skewness, leptokurtosis, fat tails as ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Applied linguistics and interpreting have much in common; however, the education of signed language interpreters in the States provides barely any applied linguistics training. Linguistic racism (linguicism) frames the education and evaluation of sign language interpreters.

Goodness‐of‐Fit Tests for Positive Quadrant Dependence
International Statistical Review, EarlyView.Summary When two random variables are positive quadrant dependent (PQD), they are more likely to assume small (or large) values simultaneously compared with when the random variables are independent. This dependence structure is of interest in many areas, including finance, actuarial science and engineering.

The Evolution of Interest‐Rate Models: From the Yield Curve to the Swaption Cube
Journal of Economic Surveys, EarlyView.ABSTRACT Interest‐rate modelling is often taught as a catalogue of competing stochastic equations, obscuring why models were created and why modern sell‐side desks use several simultaneously. This survey reorganises the field around five layers of a pricing architecture: curve construction; arbitrage‐free dynamics; volatility‐smile representation ...
