Simulation study shows improved population mean estimations in stratified random sampling, suggesting better responses with calibration methods.
Objectives: To propose estimators for the population mean considering the non-response presented in the data, utilizing an auxiliary variable with the help of both traditional and calibration estimation methods. Methods: To investigate how the suggested calibration estimators perform in the case of non-response, a simulation study has been conducted using the R software. Findings: As per the percentage relative efficiencies (%PRE) using Population- I and II, the suggested estimators outperformed the existing estimators considered here, The percentage relative efficiencies (%PRE) of the proposed estimators π¦πΜ ππ,π¦πΜ π ,π¦πΆΜ ππππππ¦πΆΜ π vary from 200.513% to 215.641%, 200.524% to 215.654%, 217.910% to 247.667% and 217.904% to 247.662%, respectively, while 158.931% to 164.414% for the existing estimator π¦πΏΜ ππ with respect to the estimator π¦π»Μ π», as shown in Table 4 for Population I. Similarly, the percentage relative efficiencies (%PRE) of the estimators with respect to π¦π»Μ π» those depicted in Table 4 vary from 144.9% to 148.3%, 237.2% to 264.7 %, 237.3 % to 264.7 %, 279.6% to 324.5% and 279.6% to 324.5% for the existing estimator π¦πΏΜ ππ, and the suggested estimators π¦πΜ ππ,π¦πΜ π ,π¦πΆΜ ππππππ¦πΆΜ π , respectively, for Population II. Novelty: The proposed method has efficiently improved the traditional existing estimatorβs precision in estimation. Using this method, we can derive more new calibrated estimators.
