So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

New Ratio Estimators for Estimating Population Mean in Simple Random Sampling using a Coefficient of Variation, Correlation Coefficient and a Regression Coefficient
2017

Abstract:

We propose new ratio estimators for estimating population mean using known auxiliary variables in this paper. To estimate the population mean of the study variable we use a known population coefficient of variation of the auxiliary variable, correlation coefficient between an interest variable and an auxiliary variable and also the sample regression coefficient of interest variable of an auxiliary variable. The expressions for the bias and mean square error (MSE) of the proposed estimators up to the first order of approximation have been obtained. The performance of proposed estimators are compared with existing estimators using both theoretical and empirical data.
