Description: Tools for extreme value modeling based on the r-largest 
    order statistics framework. The package provides functions for 
    parameter estimation via maximum likelihood, return level 
    estimation with standard errors, profile likelihood-based 
    confidence intervals, random sample generation, and entropy 
    difference tests for selecting the number of order statistics r. 
    Several r-largest order statistics models are implemented, 
    including the four-parameter kappa (rK4D), generalized logistic 
    (rGLO), generalized Gumbel (rGGD), logistic (rLD), and Gumbel 
    (rGD) distributions. The rK4D methodology is described in 
    Shin et al. (2022) <doi:10.1016/j.wace.2022.100533>, the rGLO 
    model in Shin and Park (2024) <doi:10.1007/s00477-023-02642-7>, 
    and the rGGD model in Shin and Park (2025) 
    <doi:10.1038/s41598-024-83273-y>. The underlying distributions 
    are related to the kappa distribution of Hosking (1994) 
    <doi:10.1017/CBO9780511529443>, the generalized logistic 
    distribution discussed by Ahmad et al. (1988) 
    <doi:10.1016/0022-1694(88)90015-7>, and the generalized Gumbel 
    distribution of Jeong et al. (2014) 
    <doi:10.1007/s00477-014-0865-8>. Penalized likelihood approaches 
    for extreme value estimation follow Martins and Stedinger (2000) 
    <doi:10.1029/1999WR900330> and Coles and Dixon (1999) 
    <doi:10.1023/A:1009905222644>. Selection of r is supported using 
    methods discussed in Bader et al. (2017) 
    <doi:10.1007/s11222-016-9697-3>. The package is intended for 
    hydrological, climatological, and environmental extreme value 
    analysis.
