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

2 This is the 2SLS estimator. It is called as two-stage because it looks like we take two steps by creating projected X to estimate the 2SLS estimators. We do not need to take two steps as we show in (2). We can just estimate 2SLS estimators in one stepX

Instrumental variables estimation - Wikipedia

Introduction The concept of instrumental variables was first derived by Philip G. Wright, possibly in co-authorship with his son Sewall Wright, in the context of simultaneous equations in his 1928 book The Tariff on Animal and Vegetable Oils. In 1945, Olav Reiersøl applied the same approach in the context of errors-in-variables models in his dissertation, giving the method its name.

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

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.
