WebHosmer-Lemeshow test in R. The Hosmer-Lemeshow test is a statistical test for goodness of fit for logistic regression models. According to ?hoslem.test, it deals only with binary logistic regression. However, I wonder if this test can be used to a ordered logit model which has more than 2 levels for the dependent variable. WebThe test is based on the chi-square statistic and is used to determine whether the model is a good fit for the data.

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.
