Noise variance estimation for Kalman filter

open access: yesE3S Web of Conferences, 2017
In this paper, we propose an algorithm that evaluates noise variance with a numerical integration method. For noise variance estimation, we use Krogh method with a variable integration step.

Bayesian Bootstrap in Multiple Frames

open access: yesStats, 2022
Multiple frames are becoming increasingly relevant due to the spread of surveys conducted via registers. In this regard, estimators of population quantities have been proposed, including the multiplicity estimator. In all cases, variance estimation still

Optimal variance estimation without estimating the mean function [PDF]

open access: yes, 2013
We study the least squares estimator in the residual variance estimation context. We show that the mean squared differences of paired observations are asymptotically normally distributed.

Improving the Cavalieri estimator under non-equidistant sampling and dropouts

open access: yesImage Analysis and Stereology, 2020
Motivated by the stereological problem of volume estimation from parallel section profiles, the so-called Newton-Cotes integral estimators based on random sampling nodes are analyzed.

Variance estimation for sensitivity analysis of poverty and inequality measures

open access: yesSurvey Research Methods, 2017
Estimates of poverty and inequality are often based on application of a single equivalence scale, despite the fact that a large number of different equivalence scales can be found in the literature.

Real variance estimation in iDTMC-based depletion analysis

open access: yesNuclear Engineering and Technology, 2023
The Improved Deterministic Truncation of Monte Carlo (iDTMC) is a powerful acceleration and variance reduction scheme in the Monte Carlo analysis.

Asymptotics for sliced average variance estimation

open access: yes, 2007
In this paper, we systematically study the consistency of sliced average variance estimation (SAVE). The findings reveal that when the response is continuous, the asymptotic behavior of SAVE is rather different from that of sliced inverse regression (SIR)

Power delay profile and noise variance estimation for OFDM [PDF]

open access: yes, 2006
In this letter, we present cyclic-prefix (CP) based noise-variance and power-delay-profile estimators for Orthogonal Frequency Division Multiplexing (OFDM) systems.

New Techniques for Estimating Finite Population Variance Using Ranks of Auxiliary Variable in Two-Stage Sampling

open access: yesMathematics
This article presents a new set of estimators designed to estimate the finite population variance of a study variable in two-phase sampling. These estimators utilize the information about extreme values and ranks of an auxiliary variable. Through a first-

Automatic variance control and variance estimation loops [PDF]

open access: yes, 2000
A closed loop servo approach is applied to the problem of controlling and estimating variance in nonstationary signals. The new circuit closely resembles but is not the same as, automatic gain control (AGC) which is common in radio and other circuits ...
