Estimating Population Mean in Sample Surveys
Keywords:Bias, Mean Squared Error (MSE), Relative Efficiency, Simple Random Sampling without Replacement (SRSWOR), Probability Proportional to Size (PPS) Sampling
The paper deals with a generalized estimator of population mean which includes several estimators as its particular cases. Under certain conditions, the proposed estimator is more efficient than existing estimators. Results are supported by numerical illustration.
