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.
