综合控制方法(Abadie和Gardeazabal，2003，《美国经济评论》93：113-132；Abadie，Diamond和Hainmueller，2010，《美国统计协会杂志》105：493-505)允许采用数据驱动的方法进行小样本比较研究。Synth_ronner使用Synth自动运行多个合成控制估计的过程。它在太空中进行安慰剂估计(对相同治疗期间的估计，但对所有对照单位)。推论(p值)是通过比较估计的主效应和安慰剂效应的分布来提供的。它还允许几个单元接受治疗，可能在不同的时间段。通过将预处理分为训练和验证部分，它允许自动生成结果预测值和诊断结果。此外，它还提供诊断以评估适合性，并生成结果的可视化。
The synthetic control methodology (Abadie and Gardeazabal, 2003, American Economic Review 93: 113-132; Abadie, Diamond, and Hainmueller, 2010, Journal of the American Statistical Association 105: 493-505) allows for a data-driven approach to small-sample comparative studies. synth_ronner automates the process of running multiple synthetic control estimations using synth. It conducts placebo estimates in space (estimations for the same treatment period but on all the control units). Inference (p-values) is provided by comparing the estimated main effect with the distribution of placebo effects. It also allows several units to receive treatment, possibly at different time periods. It allows automatic generation of the outcome predictors and diagnostics by splitting the pretreatment into training and validation portions. Additionally, it provides diagnostics to assess fit and generates visualizations of results.
