Conditional correlation estimation and serial dependence identification
Kewin Pączek, Damian Jelito, Marcin Pitera +1
It has been recently shown in Jaworski, P., Jelito, D. and Pitera, M. (2024), 'A note on the equivalence between the conditional uncorrelation and the independence of random variab…
Gaussian dependence structure pairwise goodness-of-fit testing based on conditional covariance and the 20/60/20 rule
Jakub Woźny, Piotr Jaworski, Damian Jelito +2
We present a novel data-oriented statistical framework that assesses the presumed Gaussian dependence structure in a pairwise setting. This refers to both multivariate normality an…
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…
