Sargan test hypothesis

WebbThe Sargan test has a null hypothesis of “the instruments as a group are exogenous”. Therefore, the higher the p-value of the Sargan statistic the better.

Here is what the output … WebbIn this sense the test answers the question: can we reject the null hypothesis that the maximum relative bias due to weak instruments is 10% (or 5%, etc.). The critical values then depend on this acceptable bias (a lower acceptable bias means that your instrument has to achieve a higher first stage F-statistic), the number of endogenous regressors and … clerk of common pleas court hamilton county https://nicoleandcompanyonline.com

WebbWe highlight the fact that the Sargan-Hansen test for GMM estimators applied to panel data is a joint test of valid orthogonality conditions and coefficient stability over time. A possible reason why the null hypothesis of valid orthogonality conditions is rejected is therefore that the slope coefficients vary over time.

Two additional tests have been recently proposed by Sarafidis, Yamagata, and Robertson (2006) and Pesaran, Ullah, and Yamagata (2006). The SYR test is based on a Sargan’s difference–type test and is relevant in short dynamic panel models. The PUY test is relevant in panel-data models with strictly exogenous regressors and normal errors.
