- In order to supply a basis for uniting the reference value standard of chinese old men s hematocrit , a research is made on the relationship between the reference value of chinese healthy old men s hematocrit and five geographical factors , which are determined by the way of wintrobe laws . it is found that altitude is the main factor affecting the reference value of chinese old men s hematocrit . as the altitude increases gradually , the reference value aslo increases gradually , and the correlation is quite obvious . applying the method of mathematical regression analysis , a regression equation is given . if geographical values are obtained in some area , the reference value of chinese old men s hematocrit of this area can be reckoned by regression equation . furthermore , according to the similarity of the reference value , taking the altitude as the main dividing basis and considering effects of other geographical factors and population distribution , china can be divided into six regions : qingzang , southwest , northwest , southeast , north and northeast region
为制定中国老年男性红细胞压积参考值的统一标准提供科学依据，收集了中国各地用温氏法测定的健康老年男性红细胞压积参考值，并对其与地理因素的关系进行了研究，发现海拔高度是影响老年男性红细胞压积参考值最主要的因素，随着海拔高度的逐渐增大，老年男性红细胞压积参考值也在逐渐增大，相关性很显著.用逐步回归分析的方法推导出了一个回归方程.如果知道了中国某地的地理因素，就可以用回归方程估算这个地区的老年男性红细胞压积参考值.依据老年男性红细胞压积参考值与地理因素的依赖关系，把中国分为青藏区、西南区、西北区、东南区、华北区、东北区等6个区 - And forecast ability was compared between the models built by selecting factors as well as orthonormalization and the other models built by stepwise regression analysis directly . the comparative result was forecast ability of model by monadic linear regression analysis and nature orthonormalization function as well as stepwise regression was stronger than the models by direct stepwise regression analysis
比较得出:通过一元一次线性回归进行因子筛选，并对其进行正交化分析，再进行逐步回归建立的预报模型比直接利用逐步回归分析建立的模型的预报功能强的多。 - Then in methodology , sample , measurements of variables and methods are defined in order to examine hypothesis above . pror example , several indicators are used to measure a variable , and stepwise regression , cluster analysis and correlation analysis compose empirical methods
然后，为了检验上述因素的影响，确定了实证研究的样本、变量指标和研究方法：选择变量指标时，采用多指标度量法，尽可能从不同角度全面反映变量；实证研究方法上主要有逐步回归分析、聚类分析和相关系数分析。 - Consequently , it is very necessary to make a general analysis about these influencing factors . at the first , this paper makes an analysis on the whole sample and draw a conclusion as follows : the stock - keeping ratio of management supervisors in ( msr ) chinese public companies is low , evenly distributed and vary acutely . secondly , this paper generalizes seven predictors from corporation ' s performance , ability of value development , property structure , character of human resource , and asset to explain the dependent variable msr by a multiply linearity equation
其次，本文从业绩、价值成长能力、股权结构、管理者人力资本特征以及公司规模五个方面出发，抽象出对管理层持股具有影响作用的七个解释变量，构造了以管理层持股比例为被解释变量的多元线性回归方程，利用spss11 . 0软件，采用全部纳入法和逐步回归分析法进行回归拟合，并采用标准参数检验( t检验和f检验)来确定其相关显著性。 - The main contents are as follows : 1 ) 3 eliminate error criterion method and step wise regression analysis method is used to analyze the errors of observation date . in the stepwise regression analysis , aging , loading and temperature which bulkily affects the dam ' s vertical deformation are selected as the regression factors , then regression equation and curve of each point are worked out
运用3准则剔除误差法和逐步回归分析法对茅坪坝的观测资料进行误差分析，在逐步回归分析中，选用对坝体竖向变形影响较大的时效、施工加载和温度作为回归因子，求出各测点的回归方程和拟合曲线。
