pandas中没有了'rolling_mean' 'rolling_std' 'ewma'

标签 pandas 没有 rolling mean std ewma 繁體版

原文原文链接

rolmean = pd.rolling_mean(timeseries, window=12) spa

rolstd = pd.rolling_std(timeseries, window=12)pandas

expwighted_avg = pd.ewma(ts_log, halflife=12)module

会有报错im

AttributeError: module 'pandas' has no attribute 'rolling_mean'time

AttributeError: module 'pandas' has no attribute 'rolling_std'版本

AttributeError: module 'pandas' has no attribute 'ewma'

这是由于pandas版本跟新了，应该改成

rolmean = timeseries.rolling(12).mean()
rolstd = timeseries.rolling(12).std()

expwighted_avg = pd.DataFrame.ewm(ts_log, halflife=12).mean()
