◦ What is the distribution? How would it look like?
 A known distribution that preserves this quality is the
power-law distribution, namely:
𝑃𝑋 𝑋 = 𝑥 ∝ 𝑥 −𝛼
 This is a good example of a micro-scale random
process (a web-site adding new links) that creates a
macro-scale distribution (the distribution of the
number of incoming links
Px with alpha=2
of all web pages).
