Survival Model-Based Imputation for Laboratory Non-Detect Data R package survlab version 0.1.0 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. Software Depends: R (>= 4.1.0) Imports: data.table (>= 1.17.0), stats, survival (>= 3.0.0), truncnorm (>= 1.0.0) Suggests: ggplot2, knitr, rmarkdown, testthat (>= 3.0.0) Luís Pereira <d57177@alunos.uevora.pt> Comprehensive R Archive Network (CRAN) Luís Pereira [aut, cre] (ORCID: <https://orcid.org/0000-0002-0628-4847>), Paulo Infante [aut] (ORCID: <https://orcid.org/0000-0002-1644-9502>), Teresa Ferreira [ths] (ORCID: <https://orcid.org/0000-0002-3900-1460>), Paulo Quaresma [ths] (ORCID: <https://orcid.org/0000-0002-5086-059X>) MIT + file LICENSE (https://CRAN.R-project.org/package=survlab/LICENSE) 2025-12-11 application/tgz https://CRAN.R-project.org/package=survlab doi:10.32614/CRAN.package.survlab en-US
