PowerLawVerläufen

PowerLawVerläufen, often translated as power-law distributions or power-law behavior, describes a relationship where a quantity's magnitude is proportional to some power of another quantity. This mathematical relationship is frequently observed in natural and social phenomena. The general form of a power-law distribution is typically expressed as P(x) ∠1/x^α, where P(x) is the probability of observing a value x, and α is a positive exponent that characterizes the distribution.

Unlike normal distributions where most values cluster around a mean, power-law distributions exhibit a heavy tail. This means that while small values are common, extremely large values occur far more frequently than predicted by a normal distribution. This characteristic makes them relevant in fields such as physics, economics, biology, and computer science. Examples include the distribution of city sizes, the frequency of word usage, the magnitude of earthquakes, and the structure of networks. Understanding power-law behavior is crucial for modeling and predicting events in these diverse areas, as it highlights the importance of rare but significant occurrences.
