Some Model Assisted Estimators Using Functional Form Calibration Approach

open access: yes, 2021
The Model assisted estimators are approximately design unbiased, consistent and provides robustness in the case of large sample sizes. The model assisted estimators result in reduction of the design variance if underlying model reasonably defines the ...

Estimation of Coefficient of Variation Using Calibrated Estimators in Double Stratified Random Sampling

open access: yesMathematics, 2023
One of the most useful indicators of relative dispersion is the coefficient of variation. The characteristics of the coefficient of variation have contributed to its widespread use in most scientific and academic disciplines, with real life applications.

Micromagnetometer Calibration for Accurate Orientation Estimation [PDF]

open access: yesIEEE Transactions on Biomedical Engineering, 2015
Micromagnetometers, together with inertial sensors, are widely used for attitude estimation for a wide variety of applications. However, appropriate sensor calibration, which is essential to the accuracy of attitude reconstruction, must be performed in advance.

Calibration Estimators of the Population Parameters Using Stratified Random Sample [PDF]

open access: yesالمجلة المصرية للسکـان وتنظيم الأسرة, 2004
One of the fundamental questions in sampling is how to use the complete auxiliary information in the estimating stag effectively. In sample surveys, recent advanced literature on estimation using auxiliary information can be classified into three main ...

Statistical Inference for the Heteroscedastic Partially Linear Varying-Coefficient Errors-in-Variables Model with Missing Censoring Indicators

open access: yesDiscrete Dynamics in Nature and Society, 2021
In this paper, we focus on heteroscedastic partially linear varying-coefficient errors-in-variables models under right-censored data with censoring indicators missing at random.

Classification of Event-Related Potentials with Regularized Spatiotemporal LCMV Beamforming

open access: yesApplied Sciences, 2022
The usability of EEG-based visual brain–computer interfaces (BCIs) based on event-related potentials (ERPs) benefits from reducing the calibration time before BCI operation. Linear decoding models, such as the spatiotemporal beamformer model, yield state-

Nonparametric Calibration for Age Estimation

open access: yesJournal of the Royal Statistical Society Series C: Applied Statistics, 2002
SUMMARY A method is proposed for the calibration of a continuous random variable when the dependent variables are a combination of continuous and categorical, and the model between the controlling variables and calibrated variable is empirically derived.

Calibration Estimation in Survey Sampling

open access: yesInternational Statistical Review, 2010
Summary Calibration estimation, where the sampling weights are adjusted to make certain estimators match known population totals, is commonly used in survey sampling. The generalized regression estimator is an example of a calibration estimator. Given the functional form of the calibration adjustment term, we establish the asymptotic equivalence ...
