After a logistic regression model has been fitted, a global test of goodness of fit of the resulting model should be performed. A test that is commonly used to assess model fit is the Hosmer-Lemeshow test, which is available in Stata and most other statistical software programs. However, it is...

The new book by Vittinghoff et al. (2005) is reviewed.

Testing goodness of fit is an important step in evaluating a statistical model. For binary logistic regression models, the Hosmer–Lemeshow goodnessof- fit test is often used. For multinomial logistic regression models, however, few tests are available. We present the mlogitgof command, which...
