Foreword

Written by two of the most prolific researchers in the area of sampling theory and survey methodology, Advances in Sampling Theory- Ratio Method of Estimation by Bentham Science Publisher is a wonderful resource for anyone who wants to work in the area of sampling theory in general and in the area of ratio and regression estimation in particular. The authors, Professor Hulya Cingi and Professor Cem Kadilar have published extensively on this topic and have drawn heavily not only from their own work, but also from the work of other researchers in the field. Most of the existing versions of the ratio and regression estimators under different sampling designs are covered in this book. Use of Taylor’s Series approximations is illustrated very effectively using different estimators. Overall, the book is a nice blend of theory and applications and can be used equally effectively both by researchers in this field and by survey data analysts
