Hosmer–lemeshow tests
WebThe 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). WebNov 5, 2024 · The Hosmer–Lemeshow test is a statistical test for goodness of fit for logistic regression models. It is used frequently in risk prediction models. The test assesses whether or not the observed event rates match expected event rates in subgroups of the model population. The Hosmer–Lemeshow test specifically identifies subgroups as the ...

These are formal tests of the null hypothesis that the fitted model is correct, and their output is a p-value--again a number between 0 and 1 with higher values indicating a better fit.
