颠覆了。。。老师还挂在嘴边的真理

有很多人真的被误导了

能再消息的说明下吗？感觉还是不太懂。

Stationary process
From Wikipedia, the free encyclopedia

In mathematics, a stationary process (or strict(ly) stationary process or strong(ly) stationary process) is a stochastic process whose joint probability distribution does not change when shifted in time. Consequently, parameters such as the mean and variance, if they are present, also do not change over time and do not follow any trends.
