Industries like finance, retail, and economics frequently use time series analysis because currency and sales are always changing. Stock market analysis is an excellent example of time series analysis in action, especially with automated trading algorithms. Likewise, time series analysis is ideal for ...

Most of the material that would be given in an introductory course on time series analysis has associated R code. Although examples are given in R, the material is not R-dependent. In courses we have given using a preliminary version of the new edition of the text, students were allowed ...
Time Series Analysis究竟有什么用?这里想引用下Hamilton在书中Preface里开篇的第一句话“Much of economics is concerned with modeling dynamics. There has been an explosion of research in this area in the last decade, as “time series econometrics” has practically come to be synonymous with “empirical...

时间序列的模式(Time series patterns) 在开始探查分析前,我们需要先确定时间序列的模式。 常见的模式有: 趋势性(Trend):数据随时间变化的呈整体上升或下降的趋势。 季节性(Seasonal):数据在每年的特定季度、月份、周、日的数据波动。 周期性(Cyclic)数据存在不固定频率的上升和下降时,表示该序列有周期性,通常与商...
