Robust estimation on a parametric model via testing

open access: yes, 2016
We are interested in the problem of robust parametric estimation of a density from $n$ i.i.d. observations. By using a practice-oriented procedure based on robust tests, we build an estimator for which we establish non-asymptotic risk bounds with respect

An Expression for Bernoulli Numbers [PDF]

open access: yesProceedings of the Glasgow Mathematical Association, 1953
In Muir's Theory of Determinants, Vol. III, pp. 232–237, there will be found accounts of papers by H. Nägelsbach, J. Hammond and J. W. L. Glaisher, in which expressions for the Bernoulli numbers are obtained in terms of determinants. In the present paper an expression for Bn will be derived which appears to be new, but which is very like some of those ...

A Note on Bernoulli Numbers and Shintani Generalized Bernoulli Polynomials [PDF]

open access: yesTransactions of the American Mathematical Society, 1996
Generalized Bernoulli polynomials were introduced by Shintani in 1976 in order to express the special values at non-positive integers of Dedekind zeta functions for totally real numbers. The coefficients of such polynomials are finite combinations of products of Bernoulli numbers which are difficult to get hold of. On the other hand, Zagier was able to

Rank‐based estimation of propensity score weights via subclassification

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Propensity score (PS) weighting estimators are widely used for causal effect estimation and enjoy desirable theoretical properties, such as consistency and potential efficiency under correct model specification. However, their performance can degrade in practice due to sensitivity to PS model misspecification.

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

open access: yesWildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...

Asymptotic goodness-of-fit tests for the Palm mark distribution of stationary point processes with correlated marks

open access: yes, 2014
We consider spatially homogeneous marked point patterns in an unboundedly expanding convex sampling window. Our main objective is to identify the distribution of the typical mark by constructing an asymptotic $\chi^2$-goodness-of-fit test.

Bayesian clustering of multivariate extremes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The asymptotic dependence structure between multivariate extreme values is fully characterized by their projections on the unit simplex. Under mild conditions, the only constraint on the resulting distributions is that their marginal means must be equal, which results in a nonparametric model that can be difficult to use in applications ...

Asymptotic theory for statistics of the Poisson--Voronoi approximation

open access: yes, 2016
This paper establishes expectation and variance asymptotics for statistics of the Poisson--Voronoi approximation of general sets, as the underlying intensity of the Poisson point process tends to infinity.

Corporate Sustainability Performance and Fraud Risk Management in Nigeria's Extractive Sector: The Moderating Role of Ownership Structure in an Evolving Environmental Policy Landscape

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Using the environmental quality cost management model, this study examines how fraud risk management (FRM) influences corporate sustainability performance (CSP) and how ownership structures moderate it. The study uses artificial neural networks (ANN) and logistic regression models to test two hypotheses. H1 demonstrates that the prevention and
