How cold is too cold? A theoretical analysis of the optimal trigger for index insurance for frost damage to crops

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

Central Limit Theorems for S-Gini and Theil Inequality Coefficients Teoremas central del límite para el S-Gini y el coeficiente de Theil

open access: yesRevista Colombiana de Estadística, 2007
The Hungarian Construction (Komlós et al. 1975) is used for getting a proof of asymptotic normality of S-Gini coefficient; this method is very interesting because it can be used to check asymptotic normality of other income inequality measures as Theil ...

Asymptotic Distribution of the Normal Sample Range

open access: yesThe Annals of Applied Probability, 1993
For a spherically symmetric, multivariate normal random sample \(X_ i\), \(i=1,2,\dots,n\), the asymptotic distribution of \(\max_{1\leq ...

ASYMPTOTIC NORMALITY OF ENTROPY ESTIMATORS [PDF]

open access: yes, 2013
Shannon's entropy plays a central role in many fields of mathematics. In the first chapter, we present a sufficient condition for the asymptotic normality of the plug-in estimator of Shannon's entropy defined on a countable alphabet.

Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Instrumental Weighted Variables

open access: yesAustrian Journal of Statistics, 2016
A motivation for the classical Instrumental Variables and the reasons for here-proposed way of their robustification are discussed. The conditions for the ?n-consistency, the existence of Bahadur representation and the asymptotic normality of the ...

Jarque-Bera test and its competitors for testing normality: A power comparison [PDF]

open access: yes
For testing normality we investigate the power of several tests, first of all, the well known test of Jarque and Bera (1980) and furthermore the tests of Kuiper (1960) and Shapiro and Wilk (1965) as well as tests of Kolmogorov-Smirnov and Cramer-von ...

Association Between Genetic Ancestry and Multiple Sclerosis Severity

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to determine whether genetic ancestry is associated with differences in the clinical course of multiple sclerosis (MS). Methods Participants with MS living in the United Kingdom >18 years old were recruited from 2021 to 2025 and genotyped from saliva using a commercial array. Genetic ancestry was inferred using

Asymptotic Properties of a Statistical Estimator of the Jeffreys Divergence: The Case of Discrete Distributions

open access: yesMathematics
We investigate the asymptotic properties of the plug-in estimator for the Jeffreys divergence, the symmetric variant of the Kullback–Leibler (KL) divergence. This study focuses specifically on the divergence between discrete distributions. Traditionally,
