PY - 2013/01/01 Y2 - 2024/03/29 TI - Improved class of estimators of finite population mean using sampling fraction and information on two auxiliary variables in sample surveys JF - Statistica JA - Stat VL - 73 IS - 3 SE - Articles DO - 10.6092/issn.1973-2201/4329 UR - https://rivista-statistica.unibo.it/article/view/4329 SP - 353-361 AB - 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 estimator and Singh’s (1967) ratio-cum-product estimator. The theoretical findings have been satisfied with an empirical study. ER -
