Abstract: In this manuscript, designing of a modified version of variables double sampling plan for the application of measureable quality characteristics is proposed and this plan is designated as ...

In this paper, we have proposed three classes of mixture ratio estimators for estimating population mean by using information on auxiliary variables and attributes simultaneously in two-phase sampling ...

This paper is an extension of Hanif, Hamad and Shahbaz estimator [1] for two-phase sampling. The aim of this paper is to develop a regression type estimator with two auxiliary variables for two-phase ...
