Overview

About

Maintained by Luís PereiraFirst published 2025-12-111 releasesCRAN page ↗GitHub ↗

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.
