two-phase sampling, three-phase sampling, stratification, ratio estimatorAbstract
In this paper a three phase sampling is proposed to estimate the population mean of character by a three phase stratified ratio estimator and some numerical results are presented to illustrate efficiency of the proposed procedure against possible alternative ones and from the expected cost optimum sample sizes on first, second and third phases are also calculated.References
