摘要: This paper considers three ratio estimators of the population mean using known correlation coefficient between study and auxiliary variables in simple random sample when some observations are missing. The suggested compared with Singh Horn (Metrika 51:267–276, 2000), Deo (Stat Pap 44:555–579, 2003) Kadilar Cingi (Commun Stat Theory Methods 37:2226–2236, 2008). They other imputation based on or a ratio. It is found that approximately unbiased for mean. Also, it turns out perform well considered this study.
