Improvement of modified ratio estimators using robust regression methods

What is it about?

The paper proposes some estimators for the population mean using robust regression methods presented in Zaman and Bulut (2018) [6] and shows that all proposed estima- tors more efficient than the robust ratio estimators under all conditions. This result is also supported by a numerical example

Why is it important?

It is developed new estimators combining robust estimators proposed by Zaman and Bulut [6] and obtained the mini- mum MSE equation for proposed estimator. Theoretically, it is demonstrated that all proposed estimators are more efficient than robust estimators proposed by Zaman and Bulut [6]
