We make full use of the advantages of singular value decomposition,avoided the shortcomings of the least-squares method which can bring ill-condition to the gray model,mentioned high stability,but also to substantially reduce the amount of computation.
研究表明该方法充分利用了奇异值分解的优点,回避了由于最小二乘法给灰色模型带来病态性的缺点,提高了模型的稳定性,同时还大大减少了计算量。
