The Hosmer-Lemeshow goodness of fit test for logistic regression

WebJan 15, 2013 · The Hosmer-Lemeshow test is a commonly used procedure for assessing goodness of fit in logistic regression. It has, for example, been widely used for evaluation of risk-scoring models. As with any statistical test, the power increases with sample size; … WebWarning about the Hosmer-Lemeshow goodness-of-fit test: It is a conservative statistic, i.e., its value is smaller than what it should be, and therefore the rejection probability of the null hypothesis is smaller. It has low power in predicting certain types of lack of fit such …
