Stein's method on the second Wiener chaos : 2-Wasserstein distance [PDF]
, 2016 In the first part of the paper we use a new Fourier technique to obtain a Stein characterizations for random variables in the second Wiener chaos. We provide the connection between this result and similar conclusions that can be derived using Malliavin ...

Fourth moment theorems on the Poisson space in any dimension
, 2018 We extend to any dimension the quantitative fourth moment theorem on the Poisson setting, recently proved by C. D\"obler and G. Peccati (2017). In particular, by adapting the exchangeable pairs couplings construction introduced by I. Nourdin and G. Zheng

Arthritis &Rheumatology, Accepted Article.Objective To identify autoantibodies in presymptomatic individuals that associate with the onset of rheumatoid arthritis (RA), and to distinguish early RA from osteoarthritis (OA), particularly in individuals lacking classic RA serological markers. Methods We analyzed serum and plasma from three cohorts: pre‐symptomatic individuals who later developed ...

RETRACTED: Learner emotions and performance in hypercasual VR games with adaptive AI difficulty
British Educational Research Journal, EarlyView.Abstract Hypercasual virtual reality games (HVRGs) are widely regarded as cost‐effective tools for rapid skill acquisition, yet the mechanisms that optimise their effectiveness and user acceptance remain insufficiently explored. This mixed‐methods empirical study investigates how playful emotions, characterised by engagement, enjoyment and anxiety ...

Density Formula in Malliavin Calculus by Using Stein’s Method and Diffusions
MathematicsLet G be a random variable of functionals of an isonormal Gaussian process X defined on some probability space. Studies have been conducted to determine the exact form of the density function of the random variable G.

Stochastic Systems, 2016 This paper provides an introduction to the Stein method framework in the context of steady-state diffusion approximations. The framework consists of three components: the Poisson equation and gradient bounds, generator coupling, and moment bounds ...

Convergence of densities of some functionals of Gaussian processes [PDF]
, 2013 The aim of this paper is to establish the uniform convergence of the densities of a sequence of random variables, which are functionals of an underlying Gaussian process, to a normal density.

The central limit problem for random vectors with symmetries
, 2005 Motivated by the central limit problem for convex bodies, we study normal approximation of linear functionals of high-dimensional random vectors with various types of symmetries. In particular, we obtain results for distributions which are coordinatewise

British Educational Research Journal, EarlyView.Abstract Beneath the Hong Kong government's enthusiasm for recruiting non‐local undergraduates—including students from the Chinese Mainland and other international regions—lies a longstanding gap in understanding the core meanings and drivers shaping the territory's expanding focus on inward international student mobility (ISM).

Stein's Method and Characters of Compact Lie Groups
, 2008 Stein's method is used to study the trace of a random element from a compact Lie group or symmetric space. Central limit theorems are proved using very little information: character values on a single element and the decomposition of the square of the ...
