Secondly, by the P-L estimation of survivor function, this paper proposed the regression models of polynomial cumulative hazard function distribution models, respectively in the case of complete date and random right censoring date; meanwhile generalized least squares estimations of unknown parameters were proposed respectively using two steps algorithm and principal component analysis algorithm.

与已有的关于多项式危险函数模型的研究成果相比，首先本文在统计模型的构造上充分考虑了累积危险函数乘积限估计量的非独立性，给出了协方差矩阵的估计；其次在模型检验方面，本文利用非参数回归分析方法，充分利用了数据本身的信息，减少了对回归关系假定的主观因素，因而分析结果更为可靠。

President of the world interconnection holds CEO Zhang Xiangning concurrently to express, internet can undertake regression certainly, do not have the district concept, Internet that was not apart from a concept from, regression is mixed completely to existing real corporeal life can the system of a service of direct correspondence.

The comparison between the obtained EC50 values and toxicity data from the literature points out the good agreement between the BOD bottle test (Raphidocelis su.) and those of nine widely used test methods, i.e., Fathead minnow, Vibrio fi., Microtox, Polytox, Spriotox, Shk1, Activated sludge, Daphina ma. and Tetrahymena. In this study, log Kow values of narcosis Ι compounds (using the BOD bottle test and nine bioassays) were reported.

实验中选定DO观测终点所求得的毒性数据与其他物种进行回归分析，回归结果则皆呈现高度相关（R2值≧0.84），这可推论出藻类与其他物种的分析方法（不含Nitrosomonas）的致毒机制有很高的相关性，且可知本试验方法不仅敏感性高且与其他的物种且有良好的相关性可做为替代性试验。

However, in regression model if there are features that are not completely relative or even completely irrelative to the problem, the difference of features' correlative degree to the problem becomes large and it may affect the performance of support vector regression machine.

基于统计学习理论的支持向量回归机有比较好的泛化能力，然而当样本含有与该问题不完全相关甚至完全无关的特征时，会使得各个特征对问题的相关程度差异很大，从而使得支持向量回归机的效果受到影响。

Based on the latest intensity data of North China that include 48 earthquakes and 139 isoseismal lines, the attenuation relationship of seismic intensity is obtained.

除了(1)式之外，有的研究者还采用了如下形式的经验公式：I=A+BM-ln(R+R0)+ε(2)由于地震烈度衰减规律是通过对烈度数据进行统计回归而得到的，而使用衰减关系式进行的直接回归会存在种种不足，因此，前人根据地震烈度衰减的特点提出了不同的统计模型和方法。

本文通过不同品种和不同地点的二次旋转回归试验，分别建立了陕农7859、冀麦5418和百泉3039三品种和辉县、武陟、修武三地点的产量、蛋白质和赖氨酸含量三个性状的二次旋转回归数学模型，并通过计算机模拟仿真，分别筛选出了三个品种和三个地点的小麦高产、优质综合农艺措施实施方案，从而为河南小麦的高产优质栽培提供了依据。

And then high performance liquid chromatography method was used to delect the blood plasma concentration of Ivermectin and Albendozale with Dual λ Absorbance Detector at the same time, which have the good lineal relation in the range of 40-640ng/ml, the equation of Ivermectin is y=0.0077+0.0117C (r=0.9994), Albendozale is Y=0.0578+0.0027C (r=0.9680). With the same method the recovery of Ivermectin and Albendozale in blood plasma concentration 60. 240. 480ng/ml were 93.5%.
