On Improvement in Estimating Population Parameter(s) Using Auxiliary Information
The purpose of writing this book is to suggest some improved estimators using
auxiliary information in sampling schemes like simple random sampling and
systematic sampling.
This volume is a collection of five papers. The following problems have been
discussed in the book:
In chapter one an estimator in systematic sampling using auxiliary
information is studied in the presence of non-response. In second chapter some
improved estimators are suggested using auxiliary information. In third chapter
some improved ratio-type estimators are suggested and their properties are
studied under second order of approximation.
In chapter four and five some estimators are proposed for estimating unknown
population parameter(s) and their properties are studied.
This book will be helpful for the researchers and students who are working in
the field of finite population estimation.Comment: 63 pages, 8 tables. Educational Publishing & Journal of Matter

Ratio Estimators in Simple Random Sampling Using Information on Auxiliary Attribute
Some ratio estimators for estimating the population mean of the variable
under study, which make use of information regarding the population proportion
possessing certain attribute, are proposed. Under simple random sampling
without replacement (SRSWOR) scheme, the expressions of bias and mean-squared
error (MSE) up to the first order of approximation are derived. The results
obtained have been illustrated numerically by taking some empirical population
considered in the literature.Comment: 7 page
