Graphing for estimator from Callaway and Sant’Anna (2020) #44

Closed Hanh7 closed 1 year ago

Hi,

1) Can you please provide a minimal working example of the issue you're having?

2) Based on the information you provided, I'm unsure how you're hoping to use DRDID. As far as I know, DRDID only considers diff-in-diff setups with 2 periods, so it does not produce an event-study. If you want to produce an event-study with dr methods, you can use the did package to estimate an event-study.

Hi there,

I am working on doubly robust DID (DRDID) estimator learning from Callaway and Sant’Anna (2020) and want to graph pre-trends for my dataset using library(pretrends). The package pretrends requires to have sigma = covariance in the function. However, the result from the DRDID seems not to have covariance matrix. I read that this package can be used for DRDID. Can you give me further instruction?

Thank you.

I have received your message and provided some of my work.

(I closed the issue there and immediately opened an issue in Pretrends, since I realized that I was asking about pretrends not the honestdid, I should put the question in the correct path).

Sorry for inconvenience!
