In search of the perfect fit: interpretation, flexible modelling, and the existing generalisations of the normal distribution
Andriette Bekker, Matthias Wagener, Muhammad Arashi
Many generalised distributions exist for modelling data with vastly diverse characteristics. However, very few of these generalisations of the normal distribution have shape parame…

Uncovering a generalised gamma distribution: from shape to interpretation
Matthias Wagener, Andriette Bekker, Mohammad Arashi +1
In this paper, we introduce the flexible interpretable gamma (FIG) distribution which has been derived by Weibullisation of the body-tail generalised normal distribution. The param…

Mastering the body and tail shape of a distribution
Matthias Wagener, Mohammad Arashi
The normal distribution and its perturbation has left an immense mark on the statistical literature. Hence, several generalized forms were developed to model different skewness, ku…
