然后，简要地介绍了多元线性回归和人工神经网络的数学算法，在此基础上建立了多元线性回归模型和神经网络模型，并依此分别对试验条件下和天然条件下冰塞的水位进行预测。

By deep analyzing the tested value of the concrete strength with the rebound method and combining with the inverse regression theory, a rebound strength curve of three-parameter inverse regression is put forward.

基于对回弹法检测混凝土强度被检测量，结合逆回归理论提出了一种逆回归三参数回弹法测强曲线模型。

By deep analyzing the tested value of the concrete strength with the rebound method and combining with the inverse regression theory,a rebound strength curve of three-parameter inverse regression is put forward.

基于对回弹法检测混凝土强度被检测量，结合逆回归理论提出了一种逆回归三参数回弹法测强曲线模型，将随机性较大的混凝土回弹值作为因变量，随机性较小的抗压强度值作为自变量，并且增加了一个位置参数，更加符合工程的实际情况。

总苞内除正常栗氨基酸含量得到相关极显著的回归方程外，其它的含量变化回归分析均未得到显著水平，空篷栗与正常栗的差异亦不显著。

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。

The average correlative coefficients of linear regression function for isochronous stress- axial strain curve are 3.92% higher than that of average correlative coefficients of linear regression function for isochronous stress- radial strain curve, so nonlinear creep property of the fine sandstone specimen in axial direction is correspondingly weaker than that in radial direction.

应力－轴向应变等时曲线线性回归函数的平均相关系数高出应力－径向应变等时曲线线性回归函数的平均相关系数3.92%，因此其轴向非线性蠕变特性相对于径向非线性蠕变特性更弱。

Was used in this study. It included the yield of five lines (L1-L5) grown in six environments (E1-E6) in 1998. Perkins and Jinks regression model and Eberhart and Russell regression model were employed to analyze genotype × environment interaction.

本研究以农业试验所1998年秋作玉米五个品系(L1-L5)在六个地区(E1-E6)所得之产量资料，使用Perkins和Jinks回归模型与Eberhart和Russell回归模型分析交感效应，结果两种模型得到的结果相同。

Step wise regression was used and equation of multiple linear regression was established.

采用逐步回归的方法，建立多元线性回归方程。

Looking to bounce back from defeat against Cesena last weekend, the Calabrian boss will be sticking to his tried and tested 4-3-3, with Lopez and Sedivic joined up front in Giampaolo's absence by either Nanni or Plasmati.

鉴于上周末对切塞纳的比赛中反败为胜，这支南方球队将会更坚持其一贯而有效的4-3-3阵型，洛佩斯和塞德维奇将取代受伤缺席的詹保罗，和纳尼或者帕斯马蒂中的一个搭档锋线。
