WebWe consider a variety of tests for testing goodness-of-fit in a parametric Cox proportional hazards (PH) model and compare their performance. Aspects of the model under test include the baseline distribution and time-invariance of covariates. We also test for the PH model itself against a certain generalization. WebThe Lipsitz test is a goodness of fit test for ordinal response logistic regression models. It involves binning the observed data into equally sized g groups based on an ordinal response score. This score is computed by summing the predicted probabilities of each subject for each outcome level multiplied by equally spaced integer weights.
