The Method of Improving Least Square Estimate in Unbiased Estimation Class
The least Square estimates are not reliable when there exists multicollinearity in adjustment model.To solve the problem statisticians improve least square estimates by biased estimates in biased estimation class.This paper presents an efficient method-Addition Restricted Condition Method(ARCM)-to solve the problem in unbiased estimation class,and proves that the method can improve least square estimates.
