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.
