Goodness-of-fit tests for the one-sided Lévy distribution based on quantile conditional moments
Kewin Pączek, Damian Jelito, Marcin Pitera +1
In this paper we introduce a novel statistical framework based on the first two quantile conditional moments that facilitates effective goodness-of-fit testing for one-sided Lévy d…

Estimation of stability index for symmetric α-stable distribution using quantile conditional variance ratios
Kewin Pączek, Damian Jelito, Marcin Pitera +1
The class of -stable distributions is widely used in various applications, especially for modelling heavy-tailed data. Although the -stable distributions have been used in pr…
