Download or read book Ratio Product Type Exponential Estimator for Estimating Finite Population Mean Using Information on Auxiliary Attribute written by Rajesh Singh and published by Infinite Study. This book was released on with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: In practice, the information regarding the population proportion possessing certain attribute is easily available, see Jhajj et.al. (2006). For estimating the population mean Y of the study variable y, following Bahl and Tuteja (1991), a ratio-product type exponential estimator has been proposed by using the known information of population proportion possessing an attribute (highly correlated with y) in simple random sampling.
Download or read book Variance Estimation Using Auxiliary Information written by A. Arcos Cebrian and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this paper is to investigate the repeated substitution method (see Srivastava, 1967) estimating population variance in finite population sample surveys. We propose an almost unbiased multivariate ratio estimator that has a smaller mean squared error than the conventional biased multivariate ratio estimator (established by Isaki, 1983) and with the same precision as the multivariate regression estimator. Furthermore, it is a computationally much more interesting estimator since to compute it we only need to have knowledge of correlation among available variables, which it is common to have in several practical situations. A comparison of the multivariate ratio estimator proposed and the multivariate regression estimator is given.

This book was released on with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we propose a new estimator for estimating the finite population mean using two auxiliary variables. The expressions for the bias and mean square error of the suggested estimator have been obtained to the first degree of approximation and some estimators are shown to be a particular member of this estimator.

Download or read book Some Finite Population Unbiased Ratio and Regression Estimators written by M. R. Mickey and published by . This book was released on 1958 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: A class of ratio and regression type estimators is given such that the estimators are unbiased for random sampling, without replacement, from a finite population. Nonnegative, unbiased estimators of estimator variance are provided for a subclass. Similar results are given for the case of generalized procedures of sampling without replacement. Efficiency is compared with comparable estimation sample selection methods for this case.
