Estimation of population variance under ranked set sampling method by using the ratio of supplementary information with study variable

HIGHLIGHTS

• who: Rabail Alam from the DepartmentAziz University have published the Article: Estimation of population variance under ranked set sampling method by using the ratio of supplementary information with study variable, in the Journal: Scientific Reports Scientific Reports
• what: The aim of this study is to propose a generalized class of estimators for population variance in RSS utilizing one auxiliary variable and comparing its efficiency with the corresponding estimators in SRS design.

SUMMARY

If α=1 then the authors have the ratio estimator of population variance from_(T1 ) and if α=-1 then the . . .
