Goodness‐of‐fit tests in proportional hazards models with random effects
Biometrical Journal, Volume 65, Issue 1, January 2023., 2023 Abstract This paper deals with testing the functional form of the covariate effects in a Cox proportional hazards model with random effects. We assume that the responses are clustered and incomplete due to right censoring. The estimation of the model under the null (parametric covariate effect) and the alternative (nonparametric effect) is performed ...
