时间序列分解法Timeseries Decomposition什么是时间序列分解法时间序列分解法是数年来一直非常有用的方法,这种方法包括谱分析时间序列分析和傅立叶级数分析等。 时间序列分解模型时间序列y可以表示为以上四个因素的函数,即: Y
moveSeries.append(series[i:i+EMA].mean()) moveSeries = np.array(moveSeries).reshape(-1)#如果项数为复数,则移动平均后数据索引无法对应原数据,要进行第2次项数为2的移动平均ifEMA %2==0: moveSeries2 = []foriinrange(0,moveSeries.shape[0]-2+1): moveSeries2.append(moveSeries[i:i+2].me...
One of the primary techniques in exploratory analysis is decomposition. This method breaks down the time-series data into its constituent components: trend, seasonality, cyclicity, and irregularities. Trend: The trend component represents the long-term movement or directionality of the data, indicating...
