POWER LAW
В статистике степенной закон (англ. power law) — это такая функциональная зависимость между двумя величинами, при которой относительное изменение одной величины приводит к пропорциональному относительному изменению другой величины, независимо от исходных значений этих величин: зависимость одной величины от другой представляет собой степенную функцию.

In statistics, a power law is a functional relationship between two quantities, where a relative change in one quantity results in a proportional relative change in the other quantity, independent of the initial size of those quantities: one quantity varies as a power of another. For instance, considering the area of a square in terms of the length of its side, if the length is doubled, the area is multiplied by a factor of four.

In venture capital and venture capital alone, the focus is on maximizing the return side of the risk/return equation. We’re all more than familiar with the “99% of startups fail” thing. From this, it’s clear that the startup world is governed by an extreme power law.

Compound interest is a power law because the relationship between the amount of time a sum of money is left in an account and the amount accumulated at the end is non-linear.
