Webb10 okt. 2024 · 4. You could perform a 2SLS approach by hand, where you estimate a Tobit model of the instrument in the first stage and use the fitted values y ^ 2 to estimate an OLS model in the second stage. The naïve standard errors won't be valid though, because they do not consider that the y ^ 2 itself is an estimate; only the variance of the residuals ...
