假设检验

Through compared with the difference of the sampling inspection's OC curves between existent and nonexistent inspection error by utilizing grouping method, we get the conclusion that all the traditional methods are designed on the premise that there is none inspection error exist, so it would terribly depress the probability of acceptance and couldn't veritably reflect the quality of the lot for inspection, if the inspection error is exist when sampling inspecting.

同时通过对集团检验错误存在与否的抽样检验特征曲线的比较，指出：以往的集团抽样检验方案设计，都是在假设无检验误差前提下设计的，在抽样检验中，若存在检验错误，会严重影响抽样检验的接收概率，使抽样检验结果不能客观地反映检验批的质量。

Then the listed companies having the corrections of accounting errors in the period from 1999 to 2004 were collected as research sample. Then the incidence which spurred the listed companies adjust errors in time was testified by methods of mean value test and multivariate linear regression. The major empirical results are summarized below: the inspection of The China Securities Regulatory Commission, other supervision outside and income quality correlated positively with it. The effect on profits correlated negatively with it. The hypothesis of the CPA firm change and assets-liabilities ratio didn't correlate with it.

Therefore, it has the important scientific research value in studying the relationship between the changing of the parameters (including the temperature, the humidity, the grain radius and so on) and the electricity and radioactivity of the medium. Applied the count statistics and the numeral value analysis, the paper analyzes, concludes and contrasts the data sufficiently through the experimentation, and acquires the following results that the resistivity and the polarizability both have the negative relationship with the temperature variety of medium from 0℃ to 200 ℃. The parallactic poalarizability is consistent with the temperature variety in the plan as well as the section, but their trends are exactly opposite. Power supply voltage has no considerable influence to the resistivity and polarizability by using duality variance analysis, however, the detecting depth and the plan position influence them greatly. Different AB/2 interval that increases by degree does not influence variance and the average value of the resistivity and the polarizability remarkably. By using the least double multiplication, the relationship of temperature-time-the influence radius of the fire source is carried up by the mathematic drawing up. After discussing their correl ation, I educe the influence radius of the fire source and carry out the 'trend analysis and forecast to the spacial changing of the temperature and the parallactic polarizability in the end.

本文通过试验并应用数理统计和数值分析等相关理论对所得到的试验数据进行了分析、归纳和对比，得出了介质温度变化在0-200℃内视电阻率和视极化率与温度均表现为负相关性；视极化率与温度在剖面和平面上的变化形态具有很好的一致性，但变化趋势相反；由二元方差分析可得供电电压对视电阻率和视极化率无显著影响，但探测深度和平面位置对视电阻率和视极化率有显著影响；通过假设检验可证不同AB／2递增间隔，对视电阻率和视极化率的方差和平均数影响都无显著性差异；应用最小二乘法对温度——时间——火源影响半径之间的关系进行了数学拟合，讨论了它们之间的相互关系，得出了火源影响的有效半径，太原理工大学硕士研究生学位论文并对温度和视极化率的空间变化作了趋势分析和预测。

In this study, the methodology of linear structural rela- tionship model of latent variable has been studied which is the first time in China. Some extended conclusions have been come up to, such as multi-factor congeneric measure model, the reliability of measurable variable and its hy- pothesis test, the relation between standardized solution and unstandardized solution, multidimensional path model with measure errors, and multilevel model of latent vari- able. Some examples have been shown to help apply these results in practice, such as the analyses of the children growth-development data, the bone density data and the health resources data by means of latent variable model. Not only have new explanations for these data been achieved, but also powerful patterns for applying the theoretical methods in medical sciences and other fields.

首次系统地研究了潜在变量的线性关系模型，对部分已有的结论作了有益的推广，如：多因子度量模型、观测变量的可靠性及其假设检验、标准解与非标准解的关系、有度量误差的多维通径模型、以及多水平资料的潜变量建模；并用实例阐述了它们的具体应用，如分析了儿童发育调查资料、人体骨骼密度调查资料以及卫生资源利用效益评价资料，不仅获得了这些资料本身一些新的解释，也为本文所研究的理论方法在医学科研以及其它领域科研中的应用提供了例证，也便于广大医学工作者掌握。
