End of course summary

Understanding, evaluating, and improving forecasts of infectious disease burden

Learning objectives

  • improve understanding of forecasting as an epidemiological task
  • familiarity with metrics for evaluating probabilistic forecasts and their properties
  • ability to score probabilistic forecasts in R
  • understanding of predictive ensembles and their properties
  • ability to create a predictive ensemble of forecasts in R
  • understanding the concept of weighted forecast ensembles

Timeline

  • forecast visualisation (session 1)
  • forecast evaluation (session 2)
  • forecast evaluation of multiple models (session 3)
  • forecast ensembles (session 4)

Key takeaways

Session 1: Forecasting

  • forecasting is the task of making unconditional statements about the future
  • meaningful forecasts are probabilistic
  • we can use visualisation understand the predictive performance of a model

Session 2: Forecast evaluation

  • we can assess forecasts using proper scoring rules
  • we can use scoring to quantify the predictive performance of different models

Session 3: Forecast ensembles

  • ensembles can combine forecasts from multiple models
  • simple ensembles often outperform indivdiual models
  • weighted ensembles can learn from past performance aiming to make better forecasts

Outlook

  • it is worth trying some of these methods here in practice to learn more about typical forecast performance
  • one way of doing so is by contributing to forecast hubs
