Package: betaregscale Type: Package Title: Beta Regression for Interval-Censored Scale-Derived Outcomes Version: 3.1.1 Authors@R: c(person(given = "José Evandeilton", family = "Lopes", role = c("aut", "cre"), email = "evandeilton@gmail.com", comment = c(ORCID = "0009-0007-5887-4084")), person(given = "Wagner Hugo", family = "Bonat", role = "aut", comment = c(ORCID = "0000-0002-0349-7054"))) Maintainer: José Evandeilton Lopes Description: Maximum-likelihood estimation of beta regression models for responses derived from bounded rating scales. Observations are treated as interval-censored on (0, 1) after a scale-to-unit transformation, and the likelihood is built from the difference of the beta CDF at the interval endpoints. The complete likelihood supports mixed censoring types: uncensored, left-censored, right-censored, and interval-censored observations. Both fixed- and variable-dispersion submodels are supported, with flexible link functions for the mean and precision components. A compiled C++ backend (via 'Rcpp' and 'RcppArmadillo') provides numerically stable, high-performance log-likelihood evaluation. Standard S3 methods (print(), summary(), coef(), fitted(), residuals(), predict(), plot(), confint(), vcov(), logLik(), AIC(), BIC(), simulate()) are available for fitted objects.
