The general feature model is one possible process interpretation of the horse race random utility model. The results are generalized to subset choices and structures of transition probabilities.

Aregular random utility is one where in any decision problem, with probability 1, the realized utility function has a unique maximizer. Hence, for a regular random utility ties are 0-probability events. WebbRANDOM UTILITY HYPOTHESIS 817 behavior, it is clear that some randomness exists across individuals.
