%description
Implements the autorelevated family of probability distributions, obtained
by applying the autorelevation transformation of Krakowski (1973)
<doi:10.1051/ro/197307V201071> and Dileepkumar and Sankaran (2022) to ten
baseline probability distributions: Weibull, Lomax, Burr XII, Gompertz,
Log-Logistic, Chen, Exponentiated Exponential, Power Lindley, Log-normal,
and Gamma. The Weibull member of the family is studied in detail by Dileep
Kumar, Shabeer, and Sankaran (2025) <doi:10.1080/01966324.2026.2665479>.
The Lomax member is studied by Sharma, Pal, Bhardwaj, and Tyagi (2026,
submitted), who establish its upside-down bathtub hazard shape. Supplies
vectorized density, distribution, survival, hazard, quantile (via the
negative branch of the Lambert W function), and random-generation
functions for all ten members of the family. It also implements Maximum
Likelihood, Maximum Product of Spacings, Least Squares, Weighted Least
Squares, and Cramer-von Mises estimation methods along with a
Kolmogorov-Smirnov goodness-of-fit test, a Total Time on Test plot, and
model selection by AIC, BIC, CAIC, and HQIC. It also includes a bundled
bladder cancer remission dataset (Lee and Wang, 2003) for illustration.
