Maximum Likelihood Estimation for the Proportional Hazards Model with Partly Interval-Censored Data
部分区间删失数据下比例风险模型的最大似然估计
Summary The maximum likelihood estimator (MLE) for the proportional hazards model with partly interval-censored data is studied. Under appropriate regularity conditions, the MLEs of the regression parameter and the cumulative hazard function are shown to be consistent and asymptotically normal. Two methods to estimate the variance–covariance matrix of the MLE of the regression parameter are considered, based on a generalized missing information principle and on a generalized…
