Package: evbsreg Type: Package Title: Local Influence Diagnostics for the Extreme-Value Birnbaum-Saunders Regression Model Version: 1.0.0 Date: 2026-06-17 Authors@R: person("Raydonal", "Ospina", email = "raydonal@de.ufpe.br", role = c("aut", "cre"), comment = c(ORCID = "0000-0002-9884-9090")) 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. The methods are described in Ospina, Lima, Barros, and Macedo (2026, submitted) and are applied to monthly maximum wind gust data from Itajai, Brazil.
