%description
Provides generalized L-moments estimation methods for the generalized
extreme value ('GEV') distribution. Implements both stationary 'GEV' and
non-stationary 'GEV11' models where location and scale parameters vary
with time. Includes various penalty functions ('Martins'-'Stedinger',
Park, Cannon, 'Coles'-Dixon) for shape parameter regularization. Also
provides model averaging estimation ('ma.gev') that combines MLE and
L-moment methods with multiple weighting schemes for robust high quantile
estimation. The 'GLME' methodology is described in Shin et al. (2025a)
<doi:10.48550/arXiv.2512.20385>. The non-stationary L-moment method is
based on Shin et al. (2025b) <doi:10.1007/s42952-025-00325-3>. The model
averaging method is described in Shin et al. (2026)
<doi:10.1007/s00477-025-03167-x>. See also 'Hosking' (1990)
<doi:10.1111/j.2517-6161.1990.tb01775.x> for L-moments theory and
'Martins' and 'Stedinger' (2000) <doi:10.1029/1999WR900330> for penalized
likelihood methods.
