%description
Implements methods for bivariate and univariate Laplace transforms of
residual lives and reversed residual lives, associated stochastic ordering
concepts, and entropy measures for reliability analysis. The package
covers: (1) Bivariate Laplace transform of residual lives and stochastic
comparisons based on the bivariate Laplace transform order of residual
lives (BLt-rl), including weak bivariate hazard rate, mean residual life,
and relative mean residual life orders, nonparametric estimation, and
NBUHR/NWUHR aging class characterisation; Jayalekshmi, Rajesh, and Nair
(2022) "Bivariate Laplace Transform of Residual Lives and Their
Properties" <doi:10.1080/03610926.2022.2085874>; (2) Bivariate Laplace
transform order of reversed residual lives (BLt-Rrl), reversed hazard
gradient, reversed mean residual life, and the associated stochastic
orders (weak bivariate reversed hazard rate, weak bivariate reversed mean
residual life); Jayalekshmi, Rajesh, and Nair (2022) "Bivariate Laplace
Transform Order and Ordering of Reversed Residual Lives"
<doi:10.1142/S0218539322500061>; (3) Univariate Laplace transform of
residual life, hazard rate, mean residual life, and the corresponding
stochastic orders (Lt-rl order, hazard rate order, MRL order), together
with a nonparametric estimator. Shannon entropy and Golomb's (1966)
information generating function are also provided. Parametric families
supported include the Gumbel bivariate exponential,
Farlie-Gumbel-Morgenstern (FGM), bivariate power, and Schur-constant
distributions. Plotting utilities and a simulation framework for
evaluating estimator performance are also provided.
