报告摘要:This paper studies clusterwise functional linear regression models with multiple functional predictors, which allow heterogeneous variation of regression patterns for different subgroups of subjects. We estimate the coefficients  based on the M-estimation with respect to possible groupings of subjects. Fast and efficient computation can be obtained by using the functional principal component basis. A Bayesian information criterion is proposed to select the unknown number of groups and shown to be consistent in model selection. We also obtain the convergence rate of the set of estimators to the set of true coefficients for all clusters. Simulation studies and a real data analysis to the Alzheimer's Disease Neuroimaging Initiative study are conducted to evaluate the finite-sample performance and practicality of the proposed method.
