按照前面说的,选择 Total = Trend + Cyclical + Noise,将原始数据分为3个部分: decomposition=seasonal_decompose(df['dau'],period=7)#(1)trend=decomposition.trend#(2)cyclical=decomposition.seasonal#(3)noise=decomposition.resid#(4) 语句里,(1)中seasonal_decompose函数的period参数表示周期天数,常取7、30...
decomposition = seasonal_decompose(df['dau'],period=7) #(1) trend = decomposition.trend #(2) cyclical = decomposition.seasonal #(3) noise = decomposition.resid #(4) 1. 2. 3. 4. 语句里,(1)中seasonal_decompose函数的period参数表示周期天数,常取7、30、7*4*3、365,约等于周、月、季、年。

The below code worked for me in Python 3 decomposition = sm.tsa.seasonal_decompose(series['Column Name'].values,freq=3) Member @rajendrasnIs.values, i.e. conversion to numpy array still necessary? This was supposed to be fixed so that thefreqkeyword overrides all period/freq checking in th...

Comparing IceNet with the multi-model median September SIE predictions from the SIO shows that, on average, IceNet either matches or outperforms the SIO in terms of mean absolute SIE error over 2012–2020 (Supplementary Fig. 2a). A year-wise decomposition further reveals IceNet’s good ...
