OGK Approach for Accurate Mean Estimation in the Presence of Outliers

Mathematics
This paper proposes a new family of robust estimators of means, depending on the Orthogonalized Gnanadesikan–Kettenring (OGK) covariance matrix. These estimators are computationally feasible and robust replacements of the Minimum Covariance Determinant ...

Prospective Inference of Central Tendency Through Data-Adaptive Mechanisms

Mathematics
In the modern age of data enrichment, it has become necessary to incorporate adaptive inference processes into survey-based estimation systems in order to achieve efficient and consistent population summaries.

Empirical Likelihood Ratio Tests for Homogeneity of Multiple Populations in the Presence of Auxiliary Information

Mathematics, 2022
The empirical likelihood ratio test (ELRT) statistic is constructed for testing the homogeneity of several nonparametric populations in the presence of some auxiliary information. It is shown—under some regularity conditions and under the null hypothesis

Median Estimation in the Presence of Auxiliary Information

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1989
SUMMARY This paper deals with the estimation, under simple random sampling, of a finite population median in the presence of an auxiliary variable. An estimator which is a simple modification of the ratio estimator for the mean is studied along with two other proposed estimators derived from a different approach.

Median Estimation with Quantile Transformations: Applications to Stratified Two-Phase Sampling

Entropy
Most traditional estimators assume normality and remain sensitive to extreme observations, which limits their usefulness in practical applications. To improve accuracy, we introduce quintile-based median estimators using transformation methods in a ...

A Unified Hybrid Estimation Strategy Using Multiple Auxiliary Transformations in Systematic Sampling with Simulation and Real-Life Applications

Axioms
Estimating the finite population mean under systematic sampling becomes challenging when auxiliary information is nonlinear, skewed, or structurally complex, as conventional linear estimators often lose efficiency.

Eliciting Auxiliary Information for Cold Start User Recommendation: A Survey

Applied Sciences, 2021
Recommender systems suggest items of interest to users based on their preferences. These preferences are typically generated from user ratings of the items. If there are no ratings for a certain user or item, it is said that there is a cold start problem,
