Improved class of estimators of finite population mean using sampling fraction and information on two auxiliary variables in sample surveys

Singh, Housila P.; Rathour, Anjana; Solanki, Ramkrishna S. - In: Statistica 73 (2013) 3, pp. 353-361

This paper suggested a generalized class of estimators using information on two auxiliary va-riables and sampling fraction in simple random sampling. The bias and mean squared error for-mulae of suggested class have been derived under large sample approximation and compared with usual unbiased...
