A stable version of this package is available on CRAN, but usually this GitHub will have the latest version.


The functions in the package are built to construct weights to make distributions more same and estimate causal effects. The primary method we recommend is by using optimal transport weights which balance distributions by design. For more information about using this package, see the vignette “Using causalOT”.
