heavy-tailed
Outliers are common
Heavy-tailed describes a probability distribution where extreme values occur more frequently than in a normal distribution.
The "tail" refers to the outer edges of a distribution curve, and a heavy tail means those edges decline slowly rather than dropping off sharply.
Financial returns, insurance claims, and natural disasters often follow heavy-tailed distributions, where rare but extreme events—market crashes, catastrophic losses—are more likely than standard models predict: The heavy-tailed nature of earthquake magnitudes makes risk assessment difficult.
