Feature request: Attrition table

[de-barros]

As a feature request, I would like to suggest checks concerning (un)systematic attrition. See Barrera-Osorio & Filmer (2016: Table 2), for an example.

Barrera-Osorio, F., & Filmer, D. (2016). Incentivizing Schooling for Learning: Evidence on the Impact of Alternative Targeting Approaches. Journal of Human Resources, 51(2), 461–499. https://doi.org/10.3368/jhr.51.2.0114-6118R1

Thanks for your suggestion, @de-barros! From what I understand, this would be a similar table to the one currently being discussed in issue #135, except that it uses a dummy for attrited units instead of treatment arms, is that correct?

If it seems similar enough, are there any modifications you would suggest we make so that it's possible to use it for this case?

Sorry I didn't see #135. Happy if you close this here and move over to #135. If you check the table from the citation, you'll notice that the main focus is on (a) the dif-in-dif (as you have it); (b) the SUR approach to jointly test for (un)systematic attrition, overall . I took a brief look but don't think (b) has been covered in your discussions so far.
