nested option in synth

[hwanoong]

Hi Brian,

Thank you very much for providing this package to us. My problem is the optimal weights for the synthetic control group are different from using "synth" and "synth_runner".

I guess the reason is synth_runner does not use "nested" option (correct?) as I see pre_rmpse is way much larger than when I use "synth" command. Can you incorporate"nested" option in your package?

It would be great if users can have "nested" option as some cases matching pre-trends is poor without this.

Best,
Hwanoong

You already can. Just pass in 'nested' and it will get passed on to synth.
