Mar 05, · Hosmer and Lemeshow () proposed grouping cases together according to their predicted values from the logistic regression model. Specifically, the predicted values are arrayed from lowest to highest, and then separated into several groups of approximately equal size. Ten groups is the standard recommendation. Lemeshow goodness-of-fit test (Hosmer & Lemeshow, ). The Hosmer-Lemeshow goodness-of-fit test is used to assess whether the number of expected events from the logistic regression model reflect the number of observed events in the data. Jul 26, · The problem with the Hosmer-Lemeshow test is precisely that it is a goodness of fit test, and goodness of fit is really only minimally relevant for most practical purposes. The logistic model is almost always a mismatch to a real-life data generating process.

A Stata program that implements the Hosmer-Lemeshow goodness of fit test, including using external prediction probabilities. Although the Hosmer-Lemeshow test is currently implemented in Stata (see lfit), hl can be used to assess predictions not just from the last regression model, but also from an external source (such as a published risk score). Jul 26, · The problem with the Hosmer-Lemeshow test is precisely that it is a goodness of fit test, and goodness of fit is really only minimally relevant for most practical purposes. The logistic model is almost always a mismatch to a real-life data generating process. Oct 25, · The Hosmer-Lemeshow goodness of fit test is based on dividing the sample up according to their predicted probabilities, or risks.
