WebThe IV method consists in two stages: first regress \(x_{K}\) on all the other regressors and all the instruments and create the fitted values series, \(\hat{x}_{K}\); second, regress the initial equation, in which \(x_{K}\) is replaced by \(\hat{x}_{K}\). Therefore, the IV method is often called two-stage least squares, or 2SLS. http://svmiller.com/blog/2024/09/instrumental-variables-2sls/ WebNote: Each column reports results from a separate least squares regression, each a first-stage regression associated with the 2SLS estimates in Table 3.
