Synthetic Control, Synth command

[Sionegael Ikeme]

Hello, I am currently working on applying the Synthetic control method on Stata. To resume my work, I am looking to estimate the effect of EU accession on the Food Production index of a country (that integrated EU in 2004).

I have one outcome variable (food production index) and five other predictor variables. I have one treated country and 12 control countries in my donor pool.

However, I am facing a problem when I am running the placebo test. I would like to exclude countries that have poor pre-intervention RMSPE in my placebo test. For instance, I would like to exclude countries, in my donor pool, that have a pre-intervention RMSPE of more than 5 times higher than the RMPSE of my treated country. Could someone help me get the graphical result of this placebo test?

Here is the coding of my synthetic control function

Welcome to the StataForum. Members on the Stata Forum generally are helpful and responsive, but they expect that you read (and adhere to) the guidelines in FAQ before posting, in your case especially #12. You are also expected to explain abbreviations that might be arcane for others, such as RMSPE. See also the posts by Akanksha Aggarwal and Bhumika Piya that received no response, perhaps for the same reason.
