WebLikewise, a natural way to generalize the parameter of interest (the ATT) from the two periods and two groups case to the multiple periods case is to define group-time average treatment effects: A T T ( g, t) = E [ Y t ( g) − Y t ( 0) G = g] This is the average effect of participating in the treatment for units in group g at time period t.
