Thanks for sharing this detailed methodological description about the African Pleistocene archaeological data and Species Distribution Models (SDMs) using GAMs. How can I assist you with this information? Are you interested in:

  • A summary or explanation of the methods?
  • Help implementing or understanding specific parts of the modeling scripts (e.g., calibration, variable selection, GAMs)?
  • Clarification on radiocarbon calibration or age filtering?
  • Guidance on how the temporal resampling and uncertainty treatment was done?
  • Something else related to the SDMs, archaeological data, or paleoclimate reconstructions?

Please specify what kind of support or information you need.

Subject of Research: Medicine, Technology and Engineering
