WebMay 23, 2024 · To estimate YNjt, we remember that a combination of units in the donor pool may approximate the characteristics of the treated unit much better than any untreated unit alone. Thus, a synthetic control is defined as a weighted average of the units in the control pool. Given the weights W=(w2,…,wJ+1) the synthetic control estimate of YNjt is Webactual control unit, the method creates a synthetic control so that the treatment can be evaluated by comparing the outcome of the treated unit with the outcome of the synthetic control unit. The synthetic control is created by selecting and then weighting together a small number of control units drawn from a pool of potential donors.
