Is there a Predict function for gsynth?

[svknair]

Hi Yiqing,

I would like to check if there is a predict option in the gsynth package. I am thinking of conducting some what-if simulations by varying the treatment time and then predicting the corresponding outcomes. For instance, what if the treatment had occurred sooner or later than the actual time. I could think of using the model output to calculate predicted values as follows:

predOutcome_t = ATT_t * D_t + factor 1_t * loading1 + factor2_t * loading2 + time_FE + unit_FE

I am able to obtain the loadings and unit fixed effects for each treated unit. But I am not sure how I can get average of loadings and fixed effects for all treated units. Do you have any suggestions for how the desired predicted outcomes can be calculated from the model output?

Thanks,
SVK

Great suggestion. We'll think about how to incorporate them in the next version. Best, Yiqing
