本文利阿太离散信号的检测理论,按照均方误差最小准则,研究经济预测技术中的移动平均法的最佳时段长的选取问题,得到了最佳时段长与所需求的经济发展趋势和偶然因素产生的干扰之间的关系,并分析了最佳时段长的选取原则。
In this paper, the detection theory of Lyapuni Discrete Signal is used to study the selection of the optimal period length for the moving average method in the economic forecasting technique according to the minimum mean square error criterion. The optimal period length and the required economic development trend and chance The relationship between the interference caused by factors, and analyzes the selection principle of the best time period.
