%description
An implementation of efficiency first conformal prediction (EFCP) and
validity first conformal prediction (VFCP) that demonstrates both validity
(coverage guarantee) and efficiency (width guarantee). To learn how to use
it, check the vignettes for a quick tutorial. The package is based on the
work by Yang Y., Kuchibhotla A.,(2021) <arxiv:2104.13871>.
