Description
The README says:
"Lastly, let Z1 be a (1 x T0) matrix containing every observation of the outcome for the treated unit in the pre-treatment period. Similarly, let Z0 be a (k x T0) matrix containing the outcome for each control unit in the pre-treatment period."
The above equation cannot satisfy variables with the listed shapes.
I think the listed shapes should instead read:
"Lastly, let Z1 be a (T0 x 1) matrix containing every observation of the outcome for the treated unit in the pre-treatment period. Similarly, let Z0 be a (T0 x J) matrix containing the outcome for each control unit in the pre-treatment period."
So that each observed outcome for the 1 intervention group is compared to the weighted average of the observed outcomes of the J control groups at each time steps in the T0 steps leading up to intervention.
Please let me know if I have missed something, because this is based on my initial studying of the code and README. Thank you!
