pysyncon 1.5.1

No project description provided

pysyncon

A python module for the synthetic control method that provides implementations of:

• Synthetic Control Method (Abadie & Gardeazabal 2003)
• Robust Synthetic Control Method (Amjad, Shah & Shen 2018)
• Augmented Synthetic Control Method (Ben-Michael, Feller & Rothstein 2021)
• Penalized Synthetic Control Method (Abadie & L'Hour 2021)

The package also provides methods for performing placebo tests and generating confidence intervals.

The implementation of the synthetic control method aims to be reconcilable with the R package Synth and similarly the implementation of the Augmented synthetic control method and the R package augsynth.

python -m pip install pysyncon
