Download or read book The Efficient Use of Supplementary Information in Finite Population Sampling written by Rajesh Singh and published by Infinite Study. This book was released on 2014 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of writing this book is to suggest some improved estimators using auxiliary information in sampling schemes like simple random sampling, systematic sampling and stratified random sampling. This volume is a collection of five papers, written by nine co-authors (listed in the order of the papers): Rajesh Singh, Mukesh Kumar, Manoj Kr. Chaudhary, Cem Kadilar, Prayas Sharma, Florentin Smarandache, Anil Prajapati, Hemant Verma, and Viplav Kr. Singh. In first paper dual to ratio-cum-product estimator is suggested and its properties are studied. In second paper an exponential ratio-product type estimator in stratified random sampling is proposed and its properties are studied under second order approximation. In third paper some estimators are proposed in two-phase sampling and their properties are studied in the presence of non-response. In fourth chapter a family of median based estimator is proposed in simple random sampling. In fifth paper some difference type estimators are suggested in simple random sampling and stratified random sampling and their properties are studied in presence of measurement error.

This book was released on with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A general family of estimators for estimating the population mean of the variable under study, which make use of known value of certain population parameter(s), is proposed. Under Simple Random Sampling Without Replacement (SRSWOR) scheme, the expressions of bias and mean squared error (MSE) up to first order of approximation are derived. Some well known estimators have been shown as particular member of this family.

Download or read book A General Class of Estimators of Population Median Using Two Auxiliary Variables in Double Sampling written by Jack Allen and published by Infinite Study. This book was released on with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we have suggested two classes of estimators for population median MY of the study character Y using information on two auxiliary characters X and Z in double sampling. It has been shown that the suggested classes of estimators are more efficient than the one suggested by Singh et al (2001). Estimators based on estimated optimum values have been also considered with their properties. The optimum values of the first phase and second phase sample sizes are also obtained for the fixed cost of survey.
Download or read book Efficiency Of Ratio And Regression Estimators Using Double Sampling written by Peter I. Ogunyinka and published by LAP Lambert Academic Publishing. This book was released on 2014-04-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes a full study on three estimators namely Simple random sampling without replacement (SRSWOR), double sampling for ratio and double sampling for regression estimators. These estimation procedures were applied to online software repository data obtained on www.download.com and www.sourceforge.net, hence, revealing the undiscovered but important application of Statistics to the improvement of software design and usage. Furthermore, primary data on household were collected with questionnaires which were administered by the staff and students of Nursing School of University College Hospital (UCH) in Nigeria. Empirical analysis was executed in studying the performances of these estimators in estimating the population mean. It was observed that double sampling with regression type estimator claims superiority over other estimators by possessing a minimum optimum variance under certain conditions. Relative efficiency and Coefficient of variation further confirmed this superiority of double sampling for regression with highest efficiency and precision respectively over double sampling for ratio and SRSWOR estimators.
Download or read book Ranked Set Sampling written by Carlos N. Bouza-Herrera and published by Academic Press. This book was released on 2018-10-16 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ranked Set Sampling: 65 Years Improving the Accuracy in Data Gathering is an advanced survey technique which seeks to improve the likelihood that collected sample data presents a good representation of the population and minimizes the costs associated with obtaining them. The main focus of many agricultural, ecological and environmental studies is the development of well designed, cost-effective and efficient sampling designs, giving RSS techniques a particular place in resolving the disciplinary problems of economists in application contexts, particularly experimental economics. This book seeks to place RSS at the heart of economic study designs. Focuses on how researchers should manipulate RSS techniques for specific applications Discusses RSS performs in popular statistical models, such as regression and hypothesis testing Includes a discussion of open theoretical research problems Provides mathematical proofs, enabling researchers to develop new models
