Large Scale Performance Test

  • CDAP
    • Jeff (@toliwaga) implemented HH level chunking for the CDAP model
    • CDAP chunking is working, but CDAP model fails on full population; Jeff investigating issue
  • NAs
    • Some choice models are resulting in all alternatives not available (see #81).
    • Jeff temporarily fixed this by allowing the model to choose an alternative, even though all alternatives are NA
    • We need to log and exit the simulation when this actually occurs so we can track down the data/expression errors
  • Logging/tracing
    • Wu (@wusun2) pointed out that we also need to remove NA alternatives from the choice set before calculating probabilities (see #81).
    • We haven't started working on logging, but we should, especially since we now need tracing to identify the bad data/expressions noted above.
    • Tracing output needs to be text, easily parsed, and importable into Excel; see #92

Next Steps

  • Continue to track down and fix issues for a full model run
  • Implement logging and tracing of an individual household

Project Admin

  • Fixing the issues in #81 is not really in the scope, but the project team agrees that our plan for moving forward is what we should be doing
