Almost Unbiased Modified Linear Regression Estimators for Estimation of Population Mean
Journal Title: Bonfring International Journal of Industrial Engineering and Management Science - Year 2012, Vol 2, Issue 2
Abstract
The present paper deals with a class of modified linear regression type estimators which are almost unbiased. We have derived their variances together with the values for which the proposed class of estimators perform better than the usual linear regression estimator. The performances of these proposed estimators are also assessed for certain natural populations available in the literature. It is observed from the numerical comparisons that the proposed estimators perform better than the existing modified ratio type estimators.
