I am running an ivreg2 estimation. I am not too sure on how to interpret these results, I will appreciate a pointer to some readings as I am getting conflicting ways of interpreting them when I google.
For instance, The joint null hypothesis is that the instruments are valid instruments, i.e., uncorrelated with the error term, and that the excluded instruments are correctly excluded from the estimated equation. Does this mean from my results, I do not reject the null, hence the instruments are valid instruments
