R package for implementing counterfactual estimators in panel fixed-effect settings. It is suitable for panel/TSCS analysis with binary treatments under (hypothetically) baseline randomization. It allows a treatment to switch on and off and limited carryover effects. It supports linear factor models—hence, a generalization of gsynth—and the matrix completion method.
Repo: GitHub (0.4.1)
Examples: R code used in the tutorial can be downloaded from here.
