Reposting because help needed in case of IV regression.

[Serena Smith]

Hello, I estimated a regression by ols and 2sls both. In ols the main independent variable of interest x, turns out to be significant. In IV it isn't significant. I checked for weak iv using weakivtest the effective F stat is 7.495<10. I also used estat endogenous, p value is high, can't reject the null of exogeneity, other stats of instrument strength are also below 10. Now, I think ols is the right model for me. But I want to compare the ols and iv estimates. Is there any way to do that. Please respond.

Serena:
you receive no reply probably because you posted a non-problem.
If no evidence of endogeneity has been detected, what's the gain in comparing OLS with IV regression?
