WebAug 31, 2015 · The Hosmer-Lemeshow test is for overall calibration error, not for any particular lack of fit such as quadratic effects. It does not properly take overfitting into account, is arbitrary to choice of bins and method of computing quantiles, and often has power that is too low. For these reasons the Hosmer-Lemeshow test is no longer … 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 … See more Motivation Logistic regression models provide an estimate of the probability of an outcome, usually designated as a "success".
