In the second chapter, I propose semi-parametric estimate to get median regression models with the measured error margin and use it to estimate the mediant of survival data.
因此在第二章，本人用半参数方法提出了协变量测量有误差时的中值回归模型，用它来估计寿命变量的中值。
The system software adopts median-value filter to reduce error and improve precision.
系统软件采用中值平均滤波法减弱测量误差，提高精度。
