摘要
In this paper we suggest three classes of regression-cum-ratio estimators for estimating population mean of variable of interest for two-phase sampling using multi-auxiliary variables for full information, partial information and no information cases. The expressions for mean square errors are derived. Theoretical comparison is given. Special cases of estimators are also identified.
