查询词典 regression function

Also, the establishment of logistic regression model proves that the choice of stock delivery valuation methods doesn't vary greatly by political affairs and cost of contract, while the establishment of multiple linear regression model bears out that there is a statistics significan ce between accounting evaluation, accounting profession judgment from listed companies' non-circulating assets value depreciation and reflux and the scale of major business income and the relation of high and low ratio of debt to equity. Yet, there is no statistic significance between the relationship of the publication of interest encouraging plan and company establishment date.

在此基础上，本文抽取了实施新会计准则体系之前2005年我国上市公司样本，通过建立有序分组的线性趋势检验模型研究证实，以0.05为显著水平，我国上市公司存货收发频繁程度与发出存货计价方法简化程度之间，并不显著存在一般认为应有的线性关系，排除了发出存货计价方法选择这一混杂因素的影响；进而，通过建立logistic回归模型证实，发出存货计价方法的选择也并不显著受政治和契约成本的影响；通过建立多元线性回归模型证实，上市公司对非流动资产减值的会计职业判断，与其主营业务收入的规模和负债权益比率的高低之间的关系有统计学意义，与是否公布股权激励计划和公司成立时间之间的关系没有统计学意义。

Formly, HDR casts classification problems and regression problems into a unified regression problem. Clustering is performed in both output space and input space at each internal node, termed "doubly clustered" and discriminants in the input space are automatically derived from the clusters in the input space. A hierarchical probability distribution model is applied to the resulting discriminating subspace at each internal node.

在图像的分类和检索中，以前的层次判别回归方法把分类和回归统一成回归问题，在每个内部节点进行输入和输出空间的双聚类，输入空间的分类子空间可以自动从聚类中获得，再用层次概率分布模型计算判别子空间，这样就构成了输入空间由粗到精的概率分布，可以准确而且快速地实现高维数据的检索。

Descriptive statistics, T test, analysis of variance, Scheffe's post hoc comparison, multiple regression, stepwise regression analysis and path analysis were used to analyze the data.

采用描述性统计分析、t检定、单因子变异数分析、Scheffe事后多重相关、多元回归、逐步回归与路径分析进行资料分析。

Firstly, it makes statistical significant testing of extra earning in declaration term of new stock. Secondly, it sets up linearity regression model of one factor to explain how much extra earning is from dividend. Finally, it sets up linearity regression model of multi-factor founding on theory analyzing of the first chapter to explain how many factors influence extra earning.

首先对新股公告期的超常收益做统计显著性检验，然后建立一元线性叵归模型，说明超常收益有多少是来自于股利，最后在第一章理论分析的基础上建立多元线性回归模型，说明这种超常收益的影响因素。

To determine the pilot dimensions on which the kinetic stabilization adjustment design of ejection seat depends,regression analysis of 292 pilots' dimensions and their combined gravity centers of pilot-seat systems were conducted. Stature and body weight were determined to be the depending parameters, and the regression equations were derived.

为确定火箭弹射座椅动力稳定调节方法设计所应依据的人体参数，对292例飞行员的人体参数及人椅系统组合重心数据进行了回归分析研究，综合确定了以体重和身高作为调节依据参数，并求出了该参数与人椅系统组合重心的回归方程。

In this paper, the function of regression matrix is estimated in a growth curve model, and the necessary and sufficient conditions that a linear estimator of the function is admissible among the class of all lin ear estimators under matrix loss are obtained.

摘 要：对增长曲线模型中回归矩阵的函数的线性估计进行了研究。在矩阵损失下，作者得到了线性估计在一切线性估计类中可容许的充要条件。

At the same time, we prove that the best linear unbiased prediction of a linear predictable variable Qy and the best linear unbiased prediction βn=(X"sV-1Xs)-1 X"sVs-1ys of regression coefficients of the finite populations βn=(X"V-1X)-1X"V-1y are admissible under matrix loss function and in the class of the linear predictions and the class that contains all predictions, and under quadratic loss function in the class of the linear predictions.

在线性预测类和一切预测类中是可容许预测，而在二次损失函数下其在线性预测类中是可容许预测。

By regression analysis of the obtained data, a relationship has been found between the bath depth and ingot height, which can be expressed by an exponential function, h(0,Y)=A e-B/Y, where A is the asymptotic value of the exponential function (when Y→∞hmax=A), B is a shape coefficient of the curve.

通过对已得数据的回归处理，找出了熔池深度h及锭高Y间的相关规律，得到h_(0，Y)=A·e_的指数函数关系，A是指数方程的渐近线，当Y+∞时h_(max=A是曲线形状系数。A和B均为重熔电流的函数，A=f_1，B=f_2，所以，h_(0，Y)=f_3。

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。
