在投資上,學會了power law,肥尾是什麼呢??
An example power law graph, being used to demonstrate ranking of popularity. To the right is the long tail, to the left are the few that dominate (also known as the 80-20 rule).
A power law is a special kind of mathematical relationship between two quantities. If one quantity is the frequency of an event, the relationship is a power-law distribution, and the frequencies decrease very slowly as the size of the event increases. For instance, an earthquake twice as large is four times as rare. If this pattern holds for earthquakes of all sizes, then the distribution is said to "scale". Power laws also describe other kinds of relationships, such as the metabolic rate of a species and its body mass (called Kleiber's law), and the size of a city and the number of patents it produces. What this relationship means is that there is no typical size in the conventional sense. Power laws are found throughout the natural and manmade worlds, and are an active area of scientific research.
