It's up to you and your particular circumstances. -weakiv- calculates weak-instrument-robust tests of the coefficient(s) on the endogenous variable(s) in an instrumental variables (IV) estimation. These tests include the Anderson-Rubin (AR) test, Kleibergen's K test, and Moreira's conditional likelihood ratio (CLR) test, and are available for linear IV, IV probit and IV tobit models. $\begingroup$ Hi Dimitriy, thanks for the response! I've tried etregress now, and it gives somewhat similar results. However, reading the Stata manual and Wooldridge (2002): "Econometric analysis of cross section and panel data" I get the impression that this sort of treatment-regression model assumes ignorability of treatment. If it's specific to -robust-, maybe have a look at the Finlay-Magnusson 2009 SJ paper cited in the weakiv help file. They say at one point that: " For linear IV models under homoskedasticity, Andrews, Moreira, and Stock (2007) provide a formula for computing the p-value function of the CLR test (which is embedded in the condivreg command).

Dear Statalisters, I have a question about weakiv. I have tried to run some simulations to understand the performance of CLR test. But in the following code with 15 instruments and 1 endogenous regressor, the result seems to be far from what it should be. weakiv now requires Stata 11 or better. Users with Stata 10, or users who want to use the previous version of weakiv (1.0), can install weakiv10, also available from SSC. weakiv now requires Stata 11 or better.

Fortunately, the authors of the popular xtabond2 and weakiv routines in Stata have recently added options that make it very easy to perform instrument strength diagnostics and generate weak instrument‐consistent confidence sets in the context of SYS‐GMM estimation.

For linear IV models, weakiv10 supports all the variance-covariance estimators supported by ivregress or ivreg2 (robust, cluster-robust, HAC, 2-way clustering, Kiefer and Driscoll-Kraay SEs, etc.). weakiv10 builds on and extends the command rivtest by Finlay and Magnusson (Stata Journal 9(3), 2009). weakiv10 is an older version of weakiv ... twostepweakiv is a Stata module that implements two-step weak-instrument-robust confidence sets based on Andrews (2018) and refined projection method for subvector inference based on Chaudhuri and Zivot (2011) for linear instrumental-variable (IV) models. There is an accompanying Stata Journal article (Sun, 2018) that provides an overview on the… in the Stata statistical software environment. Brief abstracts are provided below.
