摘要
We develop a robust inference procedure for misspecified Cox proportional hazards model under several two-phase cohort sampling designs. The asymptotic properties of the proposed approach are derived. Numerical studies are conducted to illustrate the finite sample performance. (C) 2019 Elsevier B.V. All rights reserved.
