A general class of estimators for the population mean using multi-phase sampling with the non-respondents
Öz
This paper addresses the problem of non-response when estimating the
population mean of the variable of interest. A general class of estimators is suggested for the unknown population mean of the study
variable. Two vectors of the auxiliary information under multi-phase
sampling scheme are used in presence of non response. The asymptotic
variance of the proposed class is determined and compared with some
other existing estimators theoretically and numerically. It is shown
that the proposed class of estimators is more efficient than [13] and [17]
