R package to generalize and transport causal effects.

causalTransportR : a package for bridging causal effects to new or general populations

causalTransportR implements a number of estimators to generalize and transport causal effects by reweighting doubly-robust score functions with transformations of selection scores. All nuisance functions are cross-fit using fast supervised learning algorithms.

Estimators

The ateGT function implements the following estimators by aggregating estimates of individual marginal means over different marginal $X$ distributions for the generalization and transportation case. $\mu, \pi, \rho$ are nuisance parameters fit using ML.
