Some Improvment in the Estimation of Population Mean in Cluster Sampling
Gupta and Shabbir (2008) have suggested an alternative form of ratio-type estimator for estimating the population mean. In this paper, we introduced new estimators by mixing two, stratified and cluster sampling method. Then we improved these estimators by using auxiliary variables and introducing new estimators. For sampling in infinite populations with a high geographic dispersion, the populat...
متن کاملEstimation of Subpopulation Parameters in One-stage Cluster Sampling Design
Sometimes in order to estimate population parameters such as mean and total values, we extract a random sample by cluster sampling method, and after completing sampling, we are interested in using the same sample to estimate the desired parameters in a subset of the population, which is said subpopulation. In this paper, we try to estimate subpopulation parameters in different cases when one-st...
متن کاملDesign Based Estimation of Finite Population Mean in Ranked Set Sampling
Abstract. This Article introduce method of ranked set sampling with replacement (RSSWR) in finite population and express how to computing samples of inclusion probability for this method. The Horvitz-Thompson and Hansen-Hurwtz estimators using auxiliary variables introduce for this design and use 2011-12 Urban Households Income and Income and Expenditure survey data, gathered for Tehran by stat...
متن کاملMultivariate Factor Analysis on the Students of Persian Gulf University's Educational Motivation: Two-Stage Cluster Sampling
Unfortunately, in the recent few years, decreasing the level of educational motivation among students at various levels of education has been increasing and has plagued many of the university educational units in the country and this can have devastating and irreparable effects in the near future. In this research, using statistical analysis of the number of questionnaires, social factors are i...
متن کاملHorvitz-Thompson estimator of population mean under inverse sampling designs
Inverse sampling design is generally considered to be appropriate technique when the population is divided into two subpopulations, one of which contains only few units. In this paper, we derive the Horvitz-Thompson estimator for the population mean under inverse sampling designs, where subpopulation sizes are known. We then introduce an alternative unbiased estimator, corresponding to post-st...
