This package contains enhancements to the Seasonal Trend Decomposition using Loess (STL) implementation that comes with base R, stl().

Here are some of the added features over stl():

  • Can handle NA values
  • Higher order loess smoothing (more than just local constant and linear)
  • Automated parameter choices for local quadratic
  • Frequency component smoothing beyond seasonal and trend
  • Plot methods for diagnostics

For (very) experimental inference, prediction, and variance reduction at endpoints, see the operator package.
