因为时间序列观测值的相关性是用前一次同一系列的观测值计算的,所以称为序列相关或自相关。 通过lags产生的时间序列自相关图被称为AutoCorrelation Function(自相关函数,如果直译的话,译者注),或简称ACF。这个图有时被称为相关图或自相关图。 下面是使用statsmodels库中的plot_acf()函数计算和绘制Minimum Daily Tempera...

It uses the autocorrelation function to encode all atoms of a molecule into two rotation-translation invariant vectors. The method is named ACPC (AutoCorrelation of Partial Charges). Compared to previous methods, neither using histograms nor explicitly computing the electrostatic potential field, but ...
