Sampling of alternatives: additional features #40

Open smmaurer opened 6 years ago

smmaurer commented 6 years ago

Feature wish list for sampling of alternatives in the MergedChoiceTable utility:

  1. Availability of alternatives
  2. Accepting callable for on-the-fly calculation of weights, availability, and interaction terms
  3. Representation of random state, for replicability
  4. Dedicated code path for shared weights ("buckets"), including support for a weights table indexed on secondary characteristics rather than obs/alt id's only
