This project contains software tools for conformal inference. The current emphasis is on conformal prediction in regression. Soon, we will 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 "examples" contains R code to reproduces all examples in the paper "Distribution-Free Predictive Inference for Regression". This R code relies on the "conformalInference" R package.
