摘要
文中讨论了车贝雪夫多项式值计算误差对作者以前提出的一种新的时间序列预报方法的预报结果的影响,并在此基础上对原来的计算方案作了推广,推广后的算法有利于提高预报准确率。
It is discussed that how the errors of values of Chebyshev polynomials influence the predicted value obtained from the new forecasting method of time series proposed previously by the author. Based on this result the forecasting method has been generalized. The forecast skill is able to be improved by using the generalized scheme.
