Robust PCA Synthetic Control

In this study, I propose a five-step algorithm for synthetic control method comparative studies. My builds on the model of Abadie et al., 2015 and later Amjad 2018. apply all three methods (robust PCA control, robust control) to answer hypothetical question, what would have been per capita GDP West Germany if it had not reunified with East in 1990? then algorithms two placebo Finally, check robustness. This paper demonstrates that my can outperform 2018 studies is less sensitive weights members than 2015.
