Signatures of the Anthropocene: Population Genomic Structure Detected in Pennsylvania Coyotes. [PDF]

Ecol Evol
Coyotes rapidly expanded across eastern North America and are highly dispersive ecological generalists, leading prior studies to report little spatial genetic structure. Using genome‐wide data from 1199 coyotes sampled over a decade in the northeastern United States, we detected subtle but significant population structure, with two weakly clinal ...

Second Order Expansions for High-Dimension Low-Sample-Size Data Statistics in Random Setting

Mathematics, 2020
We consider high-dimension low-sample-size data taken from the standard multivariate normal distribution under assumption that dimension is a random variable.

Asymptotic expansions for distribution of sums quasi-lattice random variables

Lietuvos Matematikos Rinkinys, 2011
Althoug Chebyshev [3] and Edeworth [5] had conceived of the formal expansions for distribution of sums of independent random variables, but only in Cramer’s work [4] was laid a proper foundation of this problem.

Edgeworth and Cornish Fisher expansions and confidence intervals for the distribution, density and

Statistica, 2013
We show that kernel density estimates of bandwidth h=h(n)→0 satisfy the Cornish-Fisher assumption with parameter m=nh. This allows Cornish-Fisher expansions about the normal for standardized and Studentized kernel density estimates.

Edgeworth Coefficients for Standard Multivariate Estimates

Axioms
I give for the first time explicit formulas for the coefficients needed for the fourth-order Edgeworth expansions of a multivariate standard estimate. I call these the Edgeworth coefficients.

An Analytic Approach to Probabilistic Load Flow Incorporating Correlation Between Non-Gaussian Random Variables

Elektronika ir Elektrotechnika, 2018
This paper presents a cumulant-based method for probabilistic load flow (PLF) analysis which incorporates correlation between input random variables. Our approach can approximate non-Gaussian variables of all kinds (e.g.

Inverting an Edgeworth Expansion

The Annals of Statistics, 1983
We provide a method for inverting a general Edgeworth expansion, so as to correct a statistic for the effects of non-normality. This technique is applied to the special case of the "Studentized" mean. Explicit formulae are given for the correction terms.
