Abstract

itsamatch is a data pre-processing procedure that identifies units not-exposed to the intervention that will best serve as matched controls for the single treatment unit, in multiple group interrupted time-series analysis (ITSA). Matches are defined by assessing balance on the baseline level and trend of each variable specified in the varlist -- where balance is determined by a user-defined minimum significance level (P-value). itsamatch generates a list of control group identifiers that can be passed on to itsa to assess treatment effects. Under the ignorability assumption, we approximate a randomized experiment by evaluating outcomes using matches that are balanced on observed pretreatment characteristics.
