This repository contains R software tools for conformal inference. The current emphasis is on conformal prediction in regression. We may eventually add tools for density estimation and classification.
The folder "conformalInference" can be installed as an R package, providing access to the software tools, and the file "conformalInference.pdf" contains documentation.
The folder "lei2018" contains R code to reproduce all examples in the paper Distribution-Free Predictive Inference for Regression by Lei, G'Sell, Rinaldo, Tibshirani, Wasserman (2018). The folder "tibshirani2019" contains R code to reproduce all examples in the paper Conformal Prediction Under Covariate Shift by Tibshirani, Barber, Candes, Ramdas (2019). This code all relies on the "conformalInference" R package.
