WebHosmer and Lemeshow ( 2000) proposed a statistic that they show, through simulation, is distributed as chi-square when there is no replication in any of the subpopulations. This test is available only for binary response models. First, the observations are sorted in increasing order of their estimated event probability.

WebOct 11, 2024 · However: "Finally, it has been observed that the results from this implementation of the binary and ordinal Hosmer-Lemeshow tests and the Lipsitz test are slightly different from the Stata implementations. It is not not yet clear why this is but is under investigation." (quote from Details docstring) WebFeb 17, 2024 · Hosmer-Lemeshow test in logistic regression. I would like to apply the Hosmer-Lemeshow test to a logistic regression model. However, I am a complete Phython newbie. Apparently there is no function to apply the test to the model? Has anyone perhaps ever made their own code? Ultimately, I'm only interested in the p-value, if that helps.
WebHosmer-Lemeshow: The Hosmer-Lemeshow test does not depend on the number of trials per row in the data as the other goodness-of-fit tests do.

WebThe Hosmer-Lemeshow test is performed by dividing the predicted probabilities into deciles (10 groups based on percentile ranks) and then computing a Pearson chi-square that compares the predicted to the observed frequencies (in a 2 × 10 table). Lower values (and nonsignificance) indicate a good fit to the data and, therefore, good overall model
WebApr 9, 2014 · Intuitively, one would expect the Pearson chi-square to be larger for models that fit the data more poorly, and that would suggest a one-sided z-test. But Osius and Rojek(1992) argued strongly for a two-sided test, and Hosmer, Lemeshow and Sturdivant (2013) have apparently agreed.
