5个生育阶段的作物水分响应模型由于数学结构和敏感指标的表达不同对于同一种作物的回归效果存在很大差异，表现出不同的适应性。 - ( 2 ) when analyzing the testing method for the " day - of - week effect " , we considered the ols regression effect and the testing power will decrease because of the different variable in real securities data . we considered the identification . estimation and hypothesis testing of the linear regression model with one rank auto - regression ( ar ( 1 ) ) error ( 3 ) we considered how investors reasonably utilize the testing result of the " day - of - week effect " to direct the investment strategies after obtained it
( 2 )在对“周内效应”的检验方法进行分析时，考虑到实际证券数据由于具有异方差性，使得利用ols进行回归将导致回归效果和检验的势降低，我们对于具有一阶自回归误差的线性回归模型，仔细讨论了该模型的识别、估计和对相应参数假设检验的方法。 - Three models are established first by linear regression analysis with the experiment data of practical ship plate . through comparisons between the three models obtained , the effect of each parameter on the local contraction , is examined , the conditions of application are estimated , and explanations are given to the error induced in the models obtained . 3
首先选择影响成型的主要变形参数，运用数理统计原理及逐步回归分析方法，对945钢板测试数据进行回归分析，建立了三种变形参数的回归模型，最后比较分析这三种回归公式的回归效果，考察回归公式中各变形参数对变形量的影响程度，给出适用条件，分析误差项产生的原因。
