The Hosmer-Lemeshow test is a classic hypothesis test for logistic regression. The null hypothesis is that the specified model is correct (that it fits well). The way the test works is by first sorting the observations by their predicted probability, and splitting them into 10 groups of equal numbers of observations (N).
