Description: Implements local influence diagnostics for the
        Extreme-Value Birnbaum-Saunders (EVBS) regression model: joint
        maximum likelihood estimation, conformal normal curvature
        diagnostics under three perturbation schemes (case-weight,
        response variable, and explanatory variable), randomized
        quantile residuals with simulation envelope, Monte Carlo
        simulation utilities, and publication-quality density and
        diagnostic plots. Version 1.1.0 adds the density, distribution
        and quantile functions, the finite upper endpoint, return
        levels and expected shortfall, block bootstrap standard errors
        for serially dependent series, local influence diagnostics for
        the generalized extreme-value regression model, and a GAMLSS
        family allowing the tail-shape parameter to depend on
        covariates. Version 1.2.0 adds a prospective control chart for
        endpoint identifiability. The methods are described in Ospina,
        Lima, Barros, and Macedo (2026, submitted) and are applied to
        monthly maximum wind gust data from Itajai, Brazil.
