摘要
本文提出了回归系数的一种新的有偏估计—广义根方估计,讨论了它的优良性,容许性、抗干扰性等性质,并给出了确定根方参数的两个方法。
To improve on the RR Estimator of regression coefficients in [4], a new biased estimator, Generalized RR Estimator, is considered. For the new estimator, superiority over the least squares estimate and RRE, admissibility an numerical stability are proved. Two methods for evaluating the ki values are introduced.
