abstract: Estimators for semi-parametric linear regression models with truncated response
  variables (fixed truncation point). The estimators implemented are the Symmetrically
  Trimmed Least Squares (STLS) estimator introduced by Powell (1986) <https://doi.org/10.2307/1914308>,
  the Quadratic Mode (QME) estimator introduced by Lee (1993) <https://doi.org/10.1016/0304-4076(93)90056-B>,
  and the Left Truncated (LT) estimator introduced by Karlsson (2006) <https://doi.org/10.1007/s00184-005-0023-x>.
