%description
Estimators for two functionals used to detect Gamma, Pareto or Lognormal
distributions, as well as distributions exhibiting similar tail behavior,
as introduced by Iwashita and Klar (2023) <doi:10.1111/stan.12316> and
Klar (2024) <doi:10.1080/00031305.2024.2413081>. One of these functionals,
g, originally proposed by Asmussen and Lehtomaa (2017)
<doi:10.3390/risks5010010>, distinguishes between log-convex and
log-concave tail behavior. Furthermore the characterization of the
lognormal distribution is based on the work of Mosimann (1970)
<doi:10.2307/2284599>. The package also includes methods for visualizing
these estimators and their associated confidence intervals across various
threshold values.
