Abstract(s)

We study similar statistical properties observed in distinct real world data. In particular, we focus on the power law (PL) distribution. We nd that some data is well tted by a single PL distribution whereas other phenomena force the use of two distinct PLs. This behavior is similar in, a priori, unrelated phenomena, such as catastrophes (terrorism, earthquakes) and variables associated to man-made systems, such as distribution of the number of words in texts or of the number of hits received by websites.
