xthdidregress vs csdid?

[Alexa Smith]

Hello,

Could somebody explain to me the differences between both commands? Also, is there a significant difference between csdid and csdid2? If so, how do I install csdid2?

Appreciate the help.

Thank you very much.

The difference between csdid2 and Csdid its speed and more options to restrict aggregations
for installation please visit my page. I will include a note on that in the GitHub repository too
Xthdidregress it’s the stata official implementation. So it’s somewhere in between in terms of speed
