Two-Stage Least Squares - Brenton Kenkel

Our goal now is to see that two-stage least squares gives us the same answer. Consider the first-stage regression, Ti = 0 + 1Zi + i. You know from your previous adventures with regression that the OLS esti-mates will be ˆ0 = T¯ Z=0 and ˆ1 = T¯Z=1 T¯Z=0.The

Theil's interpretation is most famous, and from it the name 2SLS is derived. In the first stage, the least squares method is applied to Eq. (7.3.2) and the least squares predictor Yi = PYj is obtained. In the second stage, Yj is substituted for Yj in the right-hand

ivreg: Two-Stage Least-Squares Regression with …

Overview. The ivreg package provides a comprehensive implementation of instrumental variables regression using two-stage least-squares (2SLS) estimation. The standard regression functionality (parameter estimation, inference, robust covariances, predictions, etc.) is derived from and supersedes the ivreg () function in the AER package.
