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 D
$$Y_t=\beta_1+\beta_2 X_{2t}+\beta_3 X_{3t}+\cdots+\beta_k X_{kt}+u_t,$$ In the model above the current observation of the error term ($u_t$) is a function of the previous (lagged) observation of the error term ($u_{t-1}$). That is, \begin{align*} u_t = ...
calculating individual autocorrelation values might not tell the whole story. There might not be any correlation at lag=1, but maybe there is a correlation at lag=15. It’s a good idea to make anautocorrelation plotto compare the values of the autocorrelation function (AFC) against...

In an effort to provide quantitative analysis of the large kinetic datasets resulting from these real-time studies, we applied bioinformatic approaches based on nonlinear dynamical system analysis, including limit cycle analysis and autocorrelation function, to systematically assess beat irregularity. The ...
