WebApr 9, 2014 · Intuitively, one would expect the Pearson chi-square to be larger for models that fit the data more poorly, and that would suggest a one-sided z-test. But Osius and Rojek(1992) argued strongly for a two-sided test, and Hosmer, Lemeshow and Sturdivant (2013) have apparently agreed. My own simulations also support this conclusion.
