If I understand correctly, you advise to run the usual weak IV diagnostics (i after 2SLS estimation - ivregress for instance) to determine whether instruments are strong or not. This is also a two-step regression procedure where the first stage of 2SLS is modified by regressing Y 1 on H, a N ×h submatrix spanning a. As far as we can tell, diagnostics for regression models fit by 2SLS are a relatively neglected topic, but were addressed briefly by Belsley, Kuh, and Welsch (1980, 266-68). Similar computations apply for other models such as probit.

MLE is more efficient than … I first run my 2SLS and I obtained that the effect of x1 (instrumented by z) on y is positive. ivregress supports estimation via two-stage least squares (2SLS), limited-information maximum likelihood (LIML), and generalized method of moments (GMM).
