Two-Stage least squares (2SLS) regression analysis is a statistical technique that is used in the analysis of structural equations. This technique is the extension of the OLS method. It is used when the dependent variable's error terms are correlated with the independent variables.

2: The stata command for 2SLS estimator is ivreg y (x1 = z1 z2) x2, first It is important to control for x 2; which can make exogeneity condition more likely to hold for z 1 and z 2 The option first reports the first-stage regression that regresses x1 onto z1; z2 and

Instrumental variables estimation - Wikipedia

One computational method which can be used to calculate IV estimates is two-stage least squares (2SLS or TSLS). In the first stage, each explanatory variable that is an endogenous covariate in the equation of interest is regressed on all of the exogenous variables in the model, including both exogenous covariates in the equation of interest and the excluded instruments.

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
