Estimation of mean using double sampling for stratification and multivariate auxiliary information

A class of two phase sampling estimators for ratio of two population means using multi-auxiliary characters in the presence of non-response

“…The estimation of the ratio of two population means with known population mean of auxiliary character(s) has been discussed by Hartley and Ross (1954), Singh (1965), Tripathi (1970), Tripathi and Chaurvedi (1979) and Khare (1991). It has been well known that the ratio, product and regression types of estimators are used to increase the efficiency of the estimates when population mean of the auxiliary character is known in advance.…”

“…But sometimes it has been observed in sample surveys that the population means of available auxiliary characters are not known in advance [sea Rao (1990)], in this condition it is customary to use two phase sampling for estimating the population means of the auxiliary characters. By introducing the two phase sampling scheme, Tripathi (1970), Singh (1982) and Khare (1983, 91) have proposed the estimators for estimating the ratio of two population means 𝑅 = 𝑌 � 1 𝑌 � 2 ⁄ using an auxiliary character with unknown population mean. Using two auxiliary characters with unknown population means, the estimators for estimating 𝑅 have been proposed by Tripathi and Sinha (1976) and Srivasvata et al (1988).…”

Estimation of Population Mean in Two Stage Design using Double Sampling for Stratification and Multiauxiliary Information

“…al. [6] Ige and Tripathi [1], Tripathi and Bahl [8], Singh and Vishwakarma [5] and Shabbir and Gupta [4] contributed well in the field of stratification. In this paper we propose difference and ratio estimators in two stage design using DSS and multi-auxiliary information.…”
