Webbstatistical model is a parameter set together with a function P: →P(S), which assigns to each parameter point θ ∈ a probability distribution Pθ on S. Here P(S)is the set of all probability distributions onS. In much of the following, it is important to distinguish between the model as a functionP: →P(S),and WebbIn information theory, the entropy of a random variable is the average level of "information", "surprise", or "uncertainty" inherent to the variable's possible outcomes.
