Книга: Peter I. Ogunyinka and Ademola A. Sodipo «Efficiency Of Ratio And Regression Estimators Using Double Sampling»
|
Производитель: "LAP Lambert Academic Publishing" 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... ISBN:9783659501562 Издательство: "LAP Lambert Academic Publishing" (2014)
