Maximum likelihood estimation in semiparametric selection bias models with application to AIDS vaccine trials
半参数选择偏差模型的最大似然估计及其艾滋病疫苗试验应用
The following problem is treated: given s possibly selection biased samples from an unknown distribution function, and assuming that the sampling rule weight functions for each of the samples are mathematically specified up to a common unknown finite-dimensional parameter, how can we use the data to estimate the unknown parameters? We propose a simple maximum partial likelihood method for deriving the semiparametric maximum likelihood estimator. A discussion of assumptions…
