Abstract

As a wrapper program for synth implementing synthetic control method (SCM), synth2 provides convenient utilities to automate in-space placebo test using fake treatment units, in-time placebo test using a fake treatment time, and leave-one-out robustness test that excludes one control unit with nonzero weight at a time. synth2 produces a series of graphs for visualization along the way. The command synth (available from Statistical Software Components) is required. See Yan and Chen (2021) for more details.
