# Introduction to time series and forecasting python

A key idea in time series is that of stationarity. Roughly speaking, a time series is stationary if its behaviour does not change over time. This means, for example, that the values always tend to vary about the same level and that their variability is constant over time. Stationary series have a rich theory and 1 Apr 29, 2019 · learn how to build a ARIMA model for time series forcasting using Python's statsmodels package and predict N timestamps ahead into the future.
