Best practices

From Harris et al. 2018.

  • Compare multiple models
  • Use time-series data when possible
  • Account for uncertainty
  • Use sensible predictors
  • Model unknowns as random effects
  • Forecast and assess for different horizons
  • Account for observation uncertainty
  • Validate via hindcasts
  • Publicly archive forecasts

They also illustrate:

  • Simple baseline models such as the long term average or random walk (aka "naive"), which in their data typically outcompete more complex models
  • ARIMA time-series models
  • A few types of species distribution models (SDMs), including two machine learning approaches (boosted regression trees, random forests)
  • Incorporating climate forecasts using CMIP scenarios
  • Full pipeline from data to evaluating and reporting forecasts
