A note on the p-value: the p-value is a test of significance for the null hypothesis \(H_0\) that. there is no difference in the log-odds of the outcome between the reference group (captured by the intercept) and the explanatory variable (or one of its …
Web28 sep. 2024 · Deviance and Pearson residuals are more useful when modeling group-level data. Let’s group the ICU data by unique combinations of predictor variables, refit the model, and compare the residuals to the subject-level model.
