abstract: Implementation of prediction and inference procedures for Synthetic Control
  methods using least square, lasso, ridge, or simplex-type constraints. Uncertainty
  is quantified with prediction intervals as developed in Cattaneo, Feng, and Titiunik
  (2021) <https://doi.org/10.1080/01621459.2021.1979561> for a single treated unit
  and in Cattaneo, Feng, Palomba, and Titiunik (2027) <https://doi.org/10.1162/rest_a_01588>
  for multiple treated units and staggered adoption. More details about the software
  implementation can be found in Cattaneo, Feng, Palomba, and Titiunik (2025) <https://doi.org/10.18637/jss.v113.i01>.
