%description
Conducts a goodness-of-fit test for the Weibull distribution (referred to
as the weibullness test) and furnishes parameter estimations for both the
two-parameter and three-parameter Weibull distributions. Notably, the
threshold parameter is derived through correlation from the Weibull plot.
Additionally, this package conducts goodness-of-fit assessments for the
exponential, Gumbel, and inverse Weibull distributions, accompanied by
parameter estimations. For more details, see Park (2017)
