If so have you accounted for serial correlation and the reduction in degrees of freedom brought about by correlating smoothedseries?
如果是的话，你对序列的相关性和由相关的平滑序列所导致的自由度降低作出解释了吗？

As for the stable stochastic noise component linearly superposed on the median series, it is smoothed by means of the default soft threshold wavelet de-noising.
对线性叠加在中值系列中的平稳随机噪声，用默认软阈值小波消噪平滑中值序列中的随机噪声分量。

The structure mutation during the economic process has very important influence on the analysis of non-smoothed time series.
