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. In this case, however, a p-value below some specified α level (say, .05) would indicate

WebThe Hosmer-Lemeshow Goodness-of-Fit Test. Sufficient replication within subpopulations is required to make the Pearson and deviance goodness-of-fit tests valid. When there are one or more continuous predictors in the model, the data are often too sparse to use these statistics. Hosmer and Lemeshow ( 2000) proposed a statistic that they show ... WebHosmer-Lemeshow (HL) Test. 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).
