Course Objectives

The analysis of dynamic phenomena is extremely important in economic and financial studies. The aim of the course is to provide knowledge of the classical statistical procedures for time series analysis, but also of more modern techniques, based on dynamic linear models (or state-space models). The course intends to provide a solid methodological background and data-analysis skill, with lectures in the computer room and individual and team work.  The software will be  R, freely available at  www.R-project.org. A new user-friendly R-package, dlm, has been developed for this course, for classical and Bayesian analysis of time series by dynamic linear models.


Course Content Summary

Part I.  Classical analysis of univariate time series

  • Descriptive techniques. Decomposition of a time series; trends, seasonality, cycle. Moving average models. Nonparametric techniques
  • Exponential smoothing. Forecast and model comparison
  • Stochastic models. Stationary processes.  ARMA and ARIMA models

Parte II. Dynamic linear models for time series analysis.

  • Dynamic linear models for time series analysis. Examples: non-stationary series; series with structural breaks; series with stochastic volatility; multivariate time series
  • Estimation, forecasting and control. Kalman filter
  • Examples and applications to economic and financial time series Dynamic linear models for trend, seasonality, cycle. Dynamic regression by dlm
  • Maximum likelihood estimation of unknown parameters
  • Bayesian inference. Conjugate analysis.  Unknown covariance matrices: simple models (discount factors)
  • Applications (multivariate ARMA models; dynamic regression (estimation of the term structure of interest rates), models for macroeconomic variables)
  • Bayesian inference and forecasting via MCMC. Recent developments

Detailed Description of Assessment Methods

There are no mid-term exams. Instead, there are take-home assignments (about every two weeks), and a final individual or team work on the analysis of real data (about 40% of the final grade).   Finally. there is a written and oral individual exam (about 60%).
