Examples
- Adjusted the input parameters , a set of optimal data and covariance matrices were obtained in the statistical meaning . correlative coefficients of the cross sections were plotted in three dimension pictures with origin program . in this way , the physical meaning of the covariance matrices and the correlation between the cross section data at each energy points are displayed visually
通过调整输入参数，最后得到在统计意义上最佳的推荐值及相应推荐值的协方差矩阵，并用origin程序画出相关系数的三维空间图，形象地显示了协方差矩阵的意义及各个能点之间截面的相关性。 - However , the car over a shorter event window ( - 2 , 2 ) rises to 3 . 35 % which is significant . this finding implies that , at least immediately before or after the announcement date , being acquired by the foreign company is good news for the shareholders of the target firm . as to the long - term effect of cross - border m & as , we find the average roe and eps increase in the following year of the event , which implies that inbound cross - border m & as enhance the performance of chinese target firms
但是在( - 2 , 2 )这样一个短时间的事件窗内,目标公司的累积超额收益率达到3 . 35 % ,在统计意义上显著的异于0 ,因此可以说明接受外资并购对目标公司的股东而言是一个利好消息,至少在公告日附近,发生这类事件的上市公司的二级市场表现明显好于大盘的表现。 - But statistically , the former manifests significant discriminant power while the latter does not . second , the above empirical results also show that the edf model has good performances in such developed countries as the u . s . a . , etc , however , it is inappropriate to apply the edf model in china directly . third , the empirical formula in the new accord , which links the corporate default risk with corporate asset return correlation coefficient , cannot capture the credit risk of china ’ s listed companies very well
从中本文得到了如下的一些结论:第一,从直观上看,基于会计信息的logit模型对我国上市公司的信用风险具有明显的判别能力,基于市场信息的期权理论模型? edf模型也似乎具有一定的判别能力;但从严格的统计意义上来看, logit模型仍然具有显著的判别能力,但edf模型的判别能力不明显;第二,本文的实证结果同时也说明,虽然kmv公司提出的edf模型在美国等发达国家的应用具有较为良好的表现,但将edf模型直接应用到我国显然并不适合;第三,新巴塞尔协议中将公司的违约风险与公司间资产收益率相关系数联系起来的经验公式也不能很好地捕捉中国上市公司信用风险方面的市场信息。 - By means of normal and empirical methods , this thesis analyzes the present situation systematically and thoroughly . with the sample of 146 chinese public companies , which had employed independent directors by the end of 2001 and disclosed their pay in the annual report , the possible factors influencing independent directors " pay , including company size , risk , business diversity , other senior management remuneration , industry type and area difference , are studied by multiple regression . it demonstrates that such three factors as other senior management remuneration , company size and area difference have significant influence on it
以截止2001年年底已聘任独立董事，并在当年年报中披露了独立董事报酬情况的146家上市公司为研究对象，运用回归分析等统计学方法，研究了公司规模、风险大小、经济业务的复杂程度、其他高层人员的报酬水平、地区和行业差异等因素对独立董事报酬水平的可能影响，证实上市公司其他高层人员的平均报酬水平、公司规模大小、地区差异等因素对独立董事报酬有统计意义上的显著影响。 - Aimed at the parameter estimation and model reduction problems of non - linear systems in noisy environment , a class of particle swami optimization ( pso ) approach with hypothesis test is proposed , named psoht , which estimates parameters by using pso operator in conjunction with evaluation and comparison in statistical sense to minimize mean square error function
摘要针对噪声环境下的非线性系统参数估计和模型降阶问题，提出了一种带假设检验的微粒群优化算法( psoht ) ，以最小化平均平方误差为目标，结合统计意义下的评价和比较，通过微粒群操作进行参数估计。
