Linear spectral statistics of eigenvectors of anisotropic sample covariance matrices [PDF]

open access: yesAnnales De L Institut Henri Poincare-probabilites Et Statistiques, 2020
Consider sample covariance matrices of the form $Q:=\Sigma^{1/2} X X^* \Sigma^{1/2}$, where $X=(x_{ij})$ is an $n\times N$ random matrix whose entries are independent random variables with mean zero and variance $N^{-1}$, and $\Sigma$ is a deterministic ...

Detecting spatial patterns with the cumulant function – Part 1: The theory [PDF]

open access: yesNonlinear Processes in Geophysics, 2008
In climate studies, detecting spatial patterns that largely deviate from the sample mean still remains a statistical challenge. Although a Principal Component Analysis (PCA), or equivalently a Empirical Orthogonal Functions (EOF) decomposition, is often

On the Statistics of Elsasser Increments in Solar Wind and Magnetohydrodynamic Turbulence [PDF]

open access: yesAstrophysical Journal Letters, 2022
In this Letter we investigate the dependency with scale of the empirical probability distribution functions (PDF) of Elsasser increments using large sets of WIND data (collected between 1995 and 2017) near 1 au. The empirical PDF are compared to the ones

Statistics of natural binaural sounds. [PDF]

open access: yesPLoS ONE, 2014
Binaural sound localization is usually considered a discrimination task, where interaural phase (IPD) and level (ILD) disparities at narrowly tuned frequency channels are utilized to identify a position of a sound source.

Refined Inference on the Scale Parameter of the Generalized Logistic Distribution Based on Adjusted Profile Likelihood Functions

open access: yesSymmetry, 2022
We consider inference based on the profile likelihood function for the scale parameter of the generalized logistic distribution. This distribution is a generalization of the logistic distribution, a symmetric distribution like the normal distribution ...

DETERMINANTS OF RURAL HOUSEHOLD SAVINGS BEHAVIOUR: THE CASE OF TOMATO FARMERS IN GHANA [PDF]

open access: yesReview of Agricultural and Applied Economics, 2019
Much as savings plays an important role in economic development process, it has been neglected very much in favour of credit in rural communities particularly in developing countries.

Systematic time expansion for the Kardar–Parisi–Zhang equation, linear statistics of the GUE at the edge and trapped fermions

open access: yesNuclear Physics B, 2018
We present a systematic short time expansion for the generating function of the one point height probability distribution for the KPZ equation with droplet initial condition, which goes much beyond previous studies.

Landslides triggered by the 12 January 2010 Port-au-Prince, Haiti, Mw = 7.0 earthquake: visual interpretation, inventory compiling, and spatial distribution statistical analysis [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2014
The 12 January 2010 Port-au-Prince, Haiti, earthquake (Mw= 7.0) triggered tens of thousands of landslides. The purpose of this study is to investigate the correlations of the occurrence of landslides and the thicknesses of their erosion with topographic,

Estimates of Rayleigh distribution parameters in statistical methods of quality control

open access: yesJournal of Physics: Conference Series, 2023
The paper considers the problem of estimating of a two-parameter generalization of Rayleigh distribution and finding distributions of estimates. This problem arose from the needs of statistical sampling inspection of dimensions obtained in the production

Estimating linear functionals in nonlinear regression with responses missing at random [PDF]

open access: yes, 2009
We consider regression models with parametric (linear or nonlinear) regression function and allow responses to be ``missing at random.'' We assume that the errors have mean zero and are independent of the covariates.
