Lesson 5: Smoothing and Decomposition Methods and More Practice with ARIMA models


This week we'll continue with ARIMA models and look at decomposition and smoothing methods.


After successfully completing this lesson, you should be able to:

  • Identify and interpret additive and multiplicative decompositions
  • Decompose a time series
  • Apply a lowess smoother
  • Apply a moving averages smoother
  • Apply a single exponential smoother
