Question

我想将11列和9000行以上的pandas数据帧转换为一个序列，并绘制其自相关和部分自相关函数，并以序列作为输入。 10_before代表滞后= 10，8_before代表滞后= 8，利息是滞后= 0。每行代表1个数据。

我想问问是否可以将df转换为系列，或者是否有其他方法来获取acf和pacf？谢谢！

设法得到一个这样的系列，我如何使用这个来绘制acf和pacf？

我的代码如下：

a= np.array([trade_10before,trade_9before,trade_8before,trade_7before,trade_6before,trade_5before,trade_4before,trade_3before,trade_2before,trade_1before,trade])
a = a.tolist()
a = pd.Series(a)
plot_acf(a)
plot_pacf(a)
plt.show()
