On fuzzy clustering for heavy-tailed data
2017 5th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS), 2017The fuzzy c-means method is investigated to cluster the heavy tailed data by using some measures of distance. A comparison study is provided based on time and precision. The results show that when using the Euclidean distance, the time required is less than if we used Manhattan distance, but the precision is higher when using the Manhattan distance.

A graphical diagnostic for heavy tailed data
Applied Stochastic Models in Business and Industry, 2020AbstractGraphical diagnostics are described for general heavy tailed data. This tool allows for a model free assessment of the tails of a univariate dataset a transform on the tails of the data. In addition, one can add to the basic plots comparisons of a dataset to multiple models.

Data analysis for heavy tailed multivariate samples
Communications in Statistics. Stochastic Models, 1997Summary: We propose methods of exploratory data analysis that test for joint stability of a multivariate data set. Examples are shown of how these techniques support or reject the joint stability of the sample. If these methods suggest that a data set is jointly stable, we would like to know how well methods of estimating a spectral measure work.

Bayesian analysis of jointly heavy-tailed data
2022This thesis develops novel Bayesian methodologies for statistical modelling of heavy-tailed data. Heavy tails are often found in practice, and yet they are an Achilles heel of a variety of main-stream random probability measures such as the Dirichlet process.

Flexible Heavy Tailed Distributions for Big Data
Annals of Data Science, 2017The Pareto type I distribution (also known as the power law distribution and Zipf’s law) appears to be the main distribution used to model heavy tailed phenomena in the big data literature. The Pareto type I distribution being one of the oldest heavy tailed distributions is not very flexible.

Synthetic Data via Quantile Regression for Heavy-Tailed and Heteroskedastic Data
2018Privacy protection of confidential data is a fundamental problem faced by many government organizations and research centers. It is further complicated when data have complex structures or variables with highly skewed distributions. The statistical community addresses general privacy concerns by introducing different techniques that aim to decrease ...

Heavy-tailed distributions for building stock data
Environment and Planning B: Urban Analytics and City Science, 2018The question of inferring the owner of a set of building stocks (e.g. from which country the buildings are taken) from building-related quantities like number of buildings or types of building event histories necessitates the knowledge of their distributions in order to compare them.
