摘要
对求解最小二乘估计法方程的谱修正迭代法进行了分析,指出了其在收敛方面存在的不足,并构造了一类改进的迭代方法。数据实例证实了改进的有效性。
The iteration method by correcting characteristic value for equation in the least square estimations is analyzed and its deficiency in convergence is found out.An improvement is proposed by using a kind of modification coefficient.Numerical experiences show the effectiveness of the improvement.
