1) Algorithm of stationaryization of time series consists of the following:
- A log transformation of feature variables to make data as "normal" as possible and make the statistical analysis results from this data more valid.
- Performed stationarization of time series by the differencing method with a shift equal to 1.
2) Data Plotting:
Drawn stationar data graphs using the seaborn and matplotlib libraries.
Estimated the Dickey-Fuller test to evaluate the stationarity degree.
