WebJul 20, 2024 · 1. I am having some issue understanding the behavior of such distributions when generating random numbers. I was under the impression that heavy tailed distributions have "heavier" tails, so there is more probability to observe higher values, whereas lighter tailed distributions have values more concentrated in the body of the … WebOf the several classifications which actuaries have proposed for the heaviness of loss-distribution tails, none has been generally accepted. Here we will show that the ultimate settlement rate, or asymptotic failure rate, provides a natural tripartite division into light, medium, and heavy tails.

In probability theory, a distribution is said to be stable if a linear combination of two independent random variables with this distribution has the same distribution, up to location and scale parameters. A random variable is said to be stable if its distribution is stable. The stable distribution family is also sometimes referred to as the Lévy alpha-stable distribution, after Paul Lévy, the first mathematician t… WebMar 7, 2024 · 1. The classical concept of "heavy tails" that we are usually interested in is when the tails are sufficiently heavy to give infinite variance. This occurs under power-law tail behaviour when one or both tails decay at a rate that is no faster than cubic decay. (Conversely, the variance will be finite if both tails decay faster than cubic decay.)
