Abstract

Partly interval-censored data consist of failure time observations, in which some of the failure times are
exactly observed while others are only known to lie within certain intervals. PICAFT is an R software
package that implements generalized Buckley-James estimation and one-step efficient estimation for the ac-
celerated failure time model with partly interval-censored data. Note that PICAFT uses the Rcpp package
(https://cran.r-project.org/web/packages/Rcpp/index.html) for integrating C++ code into R, as the under-
lying algorithm was written in C++.
