Flood Hazard Estimation under Nonstationarity Using the Particle Filter

open access: yesGeosciences, 2020
The presence of the nonstationarity in flow datasets has challenged the flood hazard assessment. Nonstationary tools and evaluation metrics have been proposed to deal with the nonstationarity and guide the infrastructure design and mitigation measures ...

Bootstrap BCa confidence intervals for a standardized mean difference in a paired samples design using a pooled standard deviation [PDF]

open access: yesTutorials in Quantitative Methods for Psychology
A standardized mean difference in a paired samples design using a pooled standard deviation, dp, requires knowledge of the population correlation, rho, in order to generate an accurate estimate of a noncentral t confidence interval (CI).

Point Estimation of States of Finite Quantum Systems [PDF]

open access: yes, 2006
The estimation of the density matrix of a $k$-level quantum system is studied when the parametrization is given by the real and imaginary part of the entries and they are estimated by independent measurements. It is established that the properties of the

The Zero-Adjusted Log-Symmetric Distributions: Point and Intervalar Estimation [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2023
In this paper, a new class of semi-continuous distributions called zero-adjusted log-symmetric is introduced and studied. Some properties and parameters estimation by maximum likelihood method are derived and confidence intervals (CIs) are developed.

Contrast estimation for parametric stationary determinantal point processes [PDF]

open access: yes, 2015
We study minimum contrast estimation for parametric stationary determi-nantal point processes. These processes form a useful class of models for repulsive (or regular, or inhibitive) point patterns and are already applied in numerous statistical ...

POINT ESTIMATION OF THE PROCESS CAPABILITY INDEX C(pk) [PDF]

open access: yes, 1995
In this paper point estimation of the process capability index C(pk) is considered. In order to improve on the natural estimator, a simple alternative estimator is proposed and its mean square error is evaluated ...

Point process stabilization methods and dimension estimation [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We provide an overview of stabilization methods for point processes and apply these methods to deduce a central limit theorem for statistical estimators of dimension.

Effect of Synchronizing Coordinated Base Stations on Phase Noise Estimation [PDF]

open access: yes, 2013
In this paper, we study the problem of oscillator phase noise (PN) estimation in coordinated multi-point (CoMP) transmission systems. Specifically, we investigate the effect of phase synchronization between coordinated base stations (BSs) on PN ...
