Package: survlab Type: Package Title: Survival Model-Based Imputation for Laboratory Non-Detect Data Version: 0.2.0 Authors@R: c( person("Luís", "Pereira", , "d57177@alunos.uevora.pt", role = c("aut", "cre"), comment = c(ORCID = "0000-0002-0628-4847")), person("Paulo", "Infante", role = "aut", comment = c(ORCID = "0000-0002-1644-9502")), person("Teresa", "Ferreira", role = "ths", comment = c(ORCID = "0000-0002-3900-1460")), person("Paulo", "Quaresma", role = "ths", comment = c(ORCID = "0000-0002-5086-059X")) ) Description: Implements survival-model-based imputation for censored laboratory measurements, including Tobit-type models with several distribution options. Suitable for data with values below detection or quantification limits, the package identifies the best-fitting distribution and produces realistic imputations that respect the censoring thresholds.
