Look at the point estimates and the standard errors. If a robustness check results in the same point estimates but larger standard errors, that may be perfectly fine, depending on what you changed.

WebA common exercise in empirical studies is a “robustness check”, where the researcher examines how certain “core” regression coefficient estimates behave when the regression specification is modified by adding or removing regressors. If the coefficients are plausible and robust, this is commonly interpreted as evidence of structural validity. Web10 de sept. de 2024 · We could do robustness tests by changing our initial priors and seeing if it changes the posterior much. If we try and picture changing our theta0 value, a higher value would essentially give us a wider plot with our coefficient being more likely to take on larger values in absolute terms, similar to having a large prior variance on our Beta.
