Hi, I currently have a dataset looking at 500 days, which is from 3rd April 2018 to 16th August 2019. That is for two seasons, spring and summer. This is recorded for 30000 homes in 10 EU countries. This is based on whether the homes are exposed to a specific program or not. If I were to write a standard TWFE estimator just based on this would it be:
Array
Here c denotes the home, t denotes the day. Where ac denotes the home dummy.
Then Wct is dummy for whether they undertook the program. This is the interaction term for the time dummy and treatment dummy.
pct are the control and u is the error term.

I am wondering if this is correct?
