Package: penAFT Type: Package Title: Fit the Semiparameteric Accelerated Failure Time Model with Elastic Net and Sparse Group Lasso Penalties Version: 0.3.2 Authors@R: c(person("Aaron J.", "Molstad", email = "amolstad@ufl.edu", role = c("aut", "cre"), comment = c(ORCID = "0000-0003-0645-5105")), person("Piotr M.", "Suder", role = "aut")) Description: The semiparametric accelerated failure time (AFT) model is an attractive alternative to the Cox proportional hazards model. This package provides a suite of functions for fitting one popular rank-based estimator of the semiparametric AFT model, the regularized Gehan estimator. Specifically, we provide functions for cross-validation, prediction, coefficient extraction, and visualizing both trace plots and cross-validation curves. For further details, please see Suder, P.
