Linear Regression with a Randomly Censored Covariate

censCov consists of implementations of threshold regression approaches for linear regression models with a covariate subject to random censoring, including deletion threshold regression and completion threshold regression. Reverse survival regression, which flip the role of response variable and the covariate, is also considered.


You can install and load censCov from CRAN using


You can install censCov from github with:

## install.packages("devtools")
