Outline  Random Walk and Unit-Root Test  ARIMA  Seasonal models  Nonlinear models Readings SDA chapter 9 FTS chapter 4 Stationarity condition The beauty of a stationary process is that it can be modelled with relatively few parameters. For example, we do not need a different expectation for each observation 𝑌 ; rather
