 Summary: The whole built from random parts, by random coupling, when each part has probability πi that its state is equilibrial, does not go (if not in equilibrium) equiprobably to all states but favours those "near" itself. Summary 5524Metric Hockett's metric Summary: Refusal to give a machine (or state, or input-valve, or transformation, etc) a particular value corresponds to talking about a set of machines (or states, or input-values, or transformations, etc). The set has no associated probabilities, but can use the concept of "independence". 5666.7Equilibrium probability ofRandom machineryRubin and Sitgreaves' set of transformations is fully unspecifiedSet or Ensemble and lack of specificationSpecification lack of, and set 5506 5507
