  <dc:title>Semi-Parametric Estimators of Truncated Regression Models</dc:title>
  <dc:title>R package truncSP version 1.2.4</dc:title>
  <dc:description>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) &lt;doi:10.2307/1914308&gt;, the Quadratic Mode (QME) estimator introduced by Lee (1993) &lt;doi:10.1016/0304-4076(93)90056-B&gt;, and the Left Truncated (LT) estimator introduced by Karlsson (2006) &lt;doi:10.1007/s00184-005-0023-x&gt;.</dc:description>
