Functional Additive Hazards Model with Application to COVID-19 Data-郝美玲Abstract：We propose a new functional additive hazards model to investigate potential effects of functional and scalar predictors on mortality risks, and develop a penalized least squares estimation approach for model parameters. The consistency, t...
