چکیده
|
The present paper deals with the estimation of a finite population mean in the presence of two auxiliary variables under a two-phase sampling set up. it is assumed that the population mean of one auxiliary variable is known while that of other is unknown. using the concept of predictive estimation developed by basu (1971),a general class of estimators has been proposed. analytical as well as simulation studies have been undertaken for evaluating performance of the suggested class.
