Detrending a time series

• Time series are made up of multiple components including:

  • Long-term trends
  • Seasonal patterns
  • Cyclical (but non-seasonal) patterns
  • Random noise
  • Phenomena of interest

• Detrending a time series means removing as many components as you can, leaving only the phenomena of interest left to visualize/analyze

• I recommend the {fable} package for time-series analysis
