Applied Time Series

Les objectifs du cours

The objective of the course is to study the theory, modeling, programming, and interpretation of the major time series models. Some applications to finance will be undertaken using Python. At the end of this class, students should be able to

  • Develop knowledge of basic univariate time series models appropriate for economic and financial data.
  • Learn how to specify and estimate a time series model on these data.
  • Be able to use such models for forecasting and to evaluate their performance.
  • Familiarize with common volatility modelling approaches.


Students must be enrolled in course Python Programming and must have past Introduction to Financial Econometrics
