theoretical distribution

a distribution that is derived from certain principles or assumptions by logical and mathematical reasoning, as opposed to one derived from real-world data obtained by empirical research. Examples include the normal distribution, binomial distribution, and Poisson distribution. In general, the procedures of inferential statistics involve taking one or more empirically observed distributions and referring these to an appropriate theoretical distribution. When there is correspondence between an empirical and a theoretical distribution, the latter may be used to make inferences (predictions) about the probability of future empirical events. Also called reference distribution.

rage

rage

n. intense, typically uncontrolled anger. It is usually differentiated from hostility in that it is not necessarily accompanied by destructive actions but rather by excessive expressions. In nonhuman animals, rage appears to be a late stage of aggression when normal deterrents to physical attack, such as submissive signals, are no longer effective. It generally includes rapid respiration; thrusting and jerking of limbs; and clawing, biting, and snarling.
