Description: Conducts causal inference with interactive fixed-effect
        models. It imputes counterfactuals for each treated unit using
        control group information based on a linear interactive fixed
        effects model that incorporates unit-specific intercepts
        interacted with time-varying coefficients. This method
        generalizes the synthetic control method to the case of
        multiple treated units and variable treatment periods, and
        improves efficiency and interpretability. See Xu (2017)
        <doi:10.1017/pan.2016.2> for details.
