WebAug 22, 2024 · A normal distribution is generally thought of mesokurtic, i.e. having normal kurtosis, with kurtosis of 3. Anything less than 3 is described as platykurtic ("light tailed") and larger than 3 as leptokurtic ("heavy tailed"). Some people subtract 3 from kurtosis so that 0 is a normal value.

Thus, the Pareto is a scalable distribution, whereas the thin-tailed is non-scalable.
