我对统计学和Python中的因果推理或因果关系的概念还很陌生。
我有一个 Dataframe test，如下所示：

x   y
0   0.03    315.98
1   -0.03   316.91
2   0.06    317.64
3   0.03    318.45
4   0.05    318.99
... ... ...
58  0.92    406.76
59  0.84    408.72
60  0.97    411.66
61  1.01    414.24
62  0.84    416.45

test.to_dict()给出为：

{'x': {0: 0.03,
  1: -0.03,

  59: 408.72,
  60: 411.66,
  61: 414.24,
  62: 416.45}}

在该 Dataframe 中有两个变量x和y。x是自变量，y是因变量。
我可以使用以下公式计算两者之间的相关性：

test.corr()

它返回：

x   y
x   1.000000    0.961354
y   0.961354    1.000000

这意味着，x和y之间的相关性为96%，但这并没有显示出两个变量之间的因果关系。
如何在Python中用统计学方法显示x导致y，并通过某个值来显示效果？
