Quantification of High-dimensional Non-Gaussianities and Its Implication to Fisher Analysis in Cosmology

open access: yesThe Astrophysical Journal, 2023
It is well known that the power spectrum is not able to fully characterize the statistical properties of non-Gaussian density fields. Recently, many different statistics have been proposed to extract information from non-Gaussian cosmological fields that

Multivariate Scale-Mixed Stable Distributions and Related Limit Theorems

open access: yesMathematics, 2020
In the paper, multivariate probability distributions are considered that are representable as scale mixtures of multivariate stable distributions. Multivariate analogs of the Mittag–Leffler distribution are introduced.

$0$-Hecke algebra action on the Stanley-Reisner ring of the Boolean algebra [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
We define an action of the $0$-Hecke algebra of type A on the Stanley-Reisner ring of the Boolean algebra. By studying this action we obtain a family of multivariate noncommutative symmetric functions, which specialize to the noncommutative Hall ...

The PIT-trap-A "model-free" bootstrap procedure for inference about regression models with discrete, multivariate responses. [PDF]

open access: yesPLoS ONE, 2017
Bootstrap methods are widely used in statistics, and bootstrapping of residuals can be especially useful in the regression context. However, difficulties are encountered extending residual resampling to regression settings where residuals are not ...

The Exact Joint Distribution of Concomitants of Order Statistics and Their Order Statistics under Normality

open access: yesRevstat Statistical Journal, 2013
In this work we derive the exact joint distribution of a linear combination of concomitants of order statistics and linear combinations of their order statistics in a multivariate normal distribution.

Distribution of Eigenvalues in Multivariate Statistical Analysis

open access: yesThe Annals of Statistics, 1983
Ten invariant multivariate testing problems involving the real, complex, or quaternion structure of covariance matrices are considered. In each problem the maximal invariant statistic and its distribution are described, as well as the maximum likelihood estimators and likelihood ratio test statistics.

Multi-Scale Process Monitoring Based on Time-Frequency Analysis and Feature Fusion

open access: yesFrontiers in Chemical Engineering, 2022
Data-driven process monitoring is an important tool to ensure safe production and smooth operation. Generally, implicit information can be mined through data processing and analysis algorithms to detect process disturbances on the basis of historical ...

The rate of convergence for multivariate sampling statistics [PDF]

open access: yes, 1993
A Berry-Esseen theorem for the rate of convergence of general nonlinear multivariate sampling statistics with normal limit distribution is derived via a multivariate extension of Stein's method.

A New Approach to Astronomical Data Analysis Based on Multiple Variables

open access: yesAdvances in Astronomy, 2023
Data analysis for a sample of celestial bodies generally is preceded by the completeness test in order to verify whether the sample objects are proper representatives of the corresponding part of the universe.
