Technical Tasks

  • Estimation Enhancements
    • Multiprocssing has been implemented

      • Can now run large dataset w/ multiprocessing (before could not run it at all)
      • Run time under 3 hours with 10 cores
      • Files are large, but new file formats decrease size by up to 40% (converting from "verbose" to "compact")
      • Problematic models are those that have many alternatives
        • Transposing the file helps, but looking into how easy it is to implement
