A Berry-Esseen Type Bound for the Kernel Density Estimator of Length-Biased Data [PDF]
Length-biased data are widely seen in applications. They are mostly applicable in epidemiological studies or survival analysis in medical researches. Here we aim to propose a Berry-Esseen type bound for the kernel density estimator of this kind of data ...

The fast semi-bounded kernel-diffeomorphism estimator
We introduce, by this work, a fast method to estimate probability density functions in the semi-bounded case. This new technique is a simplified version of the kernel-diffeomorphism estimator which requires complexity in the calculations.

An analysis of two dimensional integral equations of the second kind
In this article, a numerical method is used to solve the two dimensionalFredholm integral equation of the second kind with weak singular kernel using the Toeplitz matrix and product Nystrom method.

On logarithmic Sobolev inequalities for the heat kernel on the Heisenberg group
In this note, we derive a new logarithmic Sobolev inequality for the heat kernel on the Heisenberg group. The proof is inspired from the historical method of Leonard Gross with the Central Limit Theorem for a random walk.

Capturing the zero: a new class of zero-augmented distributions and multiplicative error processes [PDF]
We propose a novel approach to model serially dependent positive-valued variables which realize a non-trivial proportion of zero outcomes. This is a typical phenomenon in financial time series observed on high frequencies, such as cumulated trading ...

Funding Costs and Liquidity Creation: Does ESG Play Any Role?
ABSTRACT This study examines how banks' funding costs affect liquidity creation and whether environmental, social, and governance (ESG) performance shapes this relationship. Using panel data for 136 U.S. commercial banks from 2005 to 2022, we show that higher funding costs are associated with lower liquidity creation, indicating that more expensive ...

Herein, highly oscillatory integrals with hypersingular type singularities are studied. After transforming the original integral into a sum of line integrals over a positive semi-infinite interval, a Gauss-related quadrature rule is constructed.

ABSTRACT The agri‐food sector is vital to economic development, but it exerts significant environmental and social pressures. This study draws on the natural resource‐based view. It investigates the strategic sustainability‐performance nexus in the global food and beverage industry using a longitudinal dataset (2013–2023) of 633 firms across the EU ...
