How do you change a stationary to a non-stationary station?

A non-stationary time series can be converted to a stationary time series through a technique called differencing. Differencing series is the change between consecutive data points in the series. This is called first order differencing.

How to convert non-stationary data to stationary in Python?

You can make a non-stationary dataset to stationary by : (i) taking its difference, where from each value in the time series data we subtract the previous value. In python we can do this by using df. diff() method.
