Abstract:
|
Model uncertainty is inherent in survival analysis. We present a model combining method, Adaptive Regression by Mixing (ARM) to convexly combine survival models to account for model uncertainty. The advantage of ARM compared to other model selection and combining methods is illustrated through simulation and a study of chemotherapy for lung cancers. A theoretical result on risk bound of ARM is also presented.
