摘要
对LS估计变劣的原因进行了分析．根据该原因,运用矩阵论理论,在保持LS估计方法不变的前提下,建立了一种对变劣的LS估计进行改良的方法．实例分析表明,改良的效果是显著的．
Deteriorative reason of LS estimates is analyzed. According to the reason, making use of the matrix theory, on the premise of keeping to the method of LS estimates, a method for improving on deteriorative LS estimates is built. Example analysis makes known, the effect for improving on deteriorative LS estimates is marked.
