Heavy tail modeling and teletraffic data

SI Resnick - The Annals of Statistics, 1997 - JSTOR
… , the moment estimator discerns a light tail more effectively than the Hill estimator, and thus
it is often useful to apply the moment estimator to see if y < O, which would rule out heavy tail

The heavy-tail phenomenon in SGD

M Gurbuzbalaban, U Simsekli… - … Conference on Machine …, 2021 - proceedings.mlr.press
