WebHosmer and Lemeshow goodness of fit test. Hosmer and Lemeshow (1980) developed a goodness-of-fit statistic designed to be more appropriate to use when \(J=n\), when the number of unique covariate patterns is the same as the number of observations. The statistic is calculated in the follwing way: WebThe table below, Test Statistics, provides the actual result of the chi-square goodness-of-fit test.We can see from this table that our test statistic is statistically significant: χ 2 (2) = 49.4, p < .0005. Therefore, we can reject the null hypothesis and conclude that there are statistically significant differences in the preference of the type of sign-up gift, with less …
WebNote that for logistic regression models we can use the Cbar measure in SAS as an analogue of Cook’s distance to check for pointwise influence, and the Hosmer-Lemeshow test (see the lackfit option) to test goodness of fit for a model. Rejection of the Hosmer-Lemeshow test indicates there is a lack of fit (e.g. the model does not fit the data well). … 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 as nonlinearity in explanatory variables.
