Role of auxiliary information in estimation of population mean

Más información sobre el libro

Focusing on estimation techniques in survey sampling, the book explores the use of auxiliary information to enhance the accuracy of population mean estimates. It presents advanced classes of estimators, including improved ratio and product types, tailored for various scenarios involving known and unknown population parameters. The text evaluates the large sample properties of these estimators through empirical studies, comparing their effectiveness against conventional methods across different sample sizes, thereby demonstrating their potential for better estimation outcomes.
