%description
Implements a non-stationary extreme value analysis framework by coupling a
covariate-driven non-homogeneous Poisson process (NHPP) with (adaptive)
elastic-net regularization, analytical gradients and a lower bound on the
shape parameter. Provides methods for estimating conditional return levels
and unconditional (marginalized) return levels via parametric stochastic
integration over stable vector autoregressive VAR(p) covariate
trajectories, or non-parametric annual-block resampling. Supports
block-specific penalty controls, BIC selection along a regularization
path, Karush-Kuhn-Tucker convergence checks, time-rescaling residual
diagnostics, conditional parametric bootstrap inference, and walk-forward
assessment.
