Staff of national statistical institutes involved in the production process who want to acquire a good understanding of nowcasting methods and practices

Entry Qualifications

  • Sound command of English. Participants should be able to make short interventions and to actively participate in discussions
  • Basic knowledge of time series analysis and statistics
  • Basic knowledge of programming language R

Objective(s)

  • To provide the participants with a state of the art knowledge of the methodology and practice of nowcasting
  • To introduce the participants to the use of R to produce nowcasts for their own series.

Contents

  • Overview of nowcasting: purpose, difference with forecasting, flash estimates, coincident and leading indicators, mixed frequency data, practical examples

  • Nowcasting methods: naïve, Exponential Smoothing, (S)ARIMA(X)-models, bridge models, structural time series models, dynamic factor models, multivariate analysis, combining forecasts techniques
  • Practical exercises using R

Expected Outcome

Participants are expected to become familiar with the main methodologies used Nowcasting, understanding their potential and their limitations. After attending the course, they should also be able to implement those methods and cope with the issues that may arise in the practice of nowcasting, such as quality issues and data related issues.
