Webb12 aug. 2024 · My question is if there is any way to get the pseudo R2 or R2 for first stage equations. I can get the R2 of the second stage with the next code. Code: predict y_est, xb corr y_est lnExportaciones1. and finally I squared the correlation coeficient to get the R2 in this model. So, maybe I can do the same for the first stage predicted values, but ...
