7.3 Using the Model

At present, the action frequencies are only used in the re-weighting module (although this type of information could be useful in the betting strategy module). The only opponent information used externally is the weight array, which is used in the hand evaluation module (Chapter 5). In that context, since each subcase has a specific weight, the array is used to calculate weighted sums and to infer better estimates of hand strength (which can be expressed as the total weight of all subcases that are weaker than you, added to half the total weight of all tied subcases, divided by the total weight of all subcases). Note that when used in this fashion the weight array does not need to be normalized.
