External validation: a simulation study to compare cross-validation versus holdout or external testing to assess the performance of clinical prediction models using PET data from DLBCL patients

AIM: Clinical prediction models need to be validated. In this study, we used simulation data to compare various internal and external validation approaches to validate models. METHODS: Data of 500 patients were simulated using distributions of metabolic tumor volume, standardized uptake value, the m...
