First not taking the measurement error of covariates into account, we construct respectively structural regression models of lung function indices on the covariates. Then we use structural regression models with measurement error of multidimensional covariates to estimate synthetically the average effects of air pollution on lung function of preadolescent children.

先不考虑协变量—儿童年龄、身高、体重的测量误差，分别就儿童的各项肺功能指标对年龄、身高和体重建立结构回归模型；然后在协变量的测量误差分布相同和不同的假设下，分别建立各项肺功能指标对年龄、身高和体重的带有测量误差的结构回归模型，从而综合估计空气污染对儿童肺功能的平均影响效应。

KNN analysis was independent of the correlated regression model, but directly affected the model structure. Via KPCA as a middle layer, under the instruction of assorted result of the kernel function, the method was able to capture the high-ordered principal components among the secondary variables, and use SVR to establish a correlated regression model between the featured principal components and the primary variable.

KNN分析独立于后继回归模型，却又直接影响模型结构，KPCA作为中间层，在KNN分类结果指导下提取不同类别包含辅助变量高阶信息的特征主元，然后使用SVR建立特征主元和主导变量之间的回归模型。
