چکیده
|
In presence of non-response,a general class of estimators is proposed for estimating the population mean of the study variable with known value of some population parameter(s) of the auxiliary variable. the bias and mean squared error (mse) of the proposed strategy are derived under simple random sampling without replacement (srswor). some estimators are also obtained from proposed strategy by giving suitable values to the constants used. comparisons of the proposed strategy with the usual unbiased estimator and other estimators have been made. an empirical study is carried out to demonstrate the performance of the proposed estimator.
