时间序列预测法(Time Series Forecasting Method) 什么是时间序列预测法? 一种历史资料延伸预测,也称历史引伸预测法。是以时间数列所能反映的社会经济现象的发展过程和规律性,进行引伸外推,预测其发展趋势的方法。 时间序列,也叫时间数列、历史复数或动态数列。它是将某种统计指标的数值,按时间先后顺序排到所形成的...
APICS 词典time series forecasting–A forecasting method that projects historical data patterns into the future. Involves the assumption that the near-term future will be like the recent past.时间序列预测–将历史数据模式预测到未来的预测方法。这涉及到一个假设,即近期的未来将与最近的过去类似。 什么是时...
1)Average method 这个预测方法的思想很简单:未来的预测值 = 过去历史数值的平均值。公式如下: 2)Naïve method 这个方法如它的名字一样,思想更加简单:未来的预测值 = 时间序列中上一个观测值。公式如下: 听说这个方法,在很多经济和金融领域的时间序列预测分析中表现很好。 3)Seasonal naïve method 跟方法2类...
