censored is a parsnip extension package which provides engines for various models for censored regression and survival analysis.
Installation
You can install the released version of censored from CRAN with:
install.packages("censored")And the development version from GitHub with:
# install.packages("pak")
pak::pak("tidymodels/censored")Available models, engines, and prediction types
censored provides engines for the models in the following table. For examples, please see Fitting and Predicting with censored.
The time to event can be predicted with type = "time", the survival probability with type = "survival", the linear predictor with type = "linear_pred", the quantiles of the event time distribution with type = "quantile", and the hazard with type = "hazard".
