观测值

• The extreme values which lies in the tail are some rarely happened events that have significant influence . extreme value theory ( evt ) is the statistical model to study the behavior of extreme v alues
  分布在尾部的点都是一些极少发生但又具有显著影响的观测值，或者称为极值，极值理论是对这些极值提供统计分析的模型。
• The incremental method is used to analyze the observation data . the calculated values and the observed values are approximate . it reveals that the incremental method can reflect the dam ' s behavior law
  采用增量方法对观测资料进行分析，各计算值和观测值吻合较好，表明增量方法能够反映外荷作用下大坝自身的变形和应力规律。
• Conclusion modeling the covariance structure is especially important for analysis of repeated measures data because measurements taken close in time are potentially more highly correlated than those taken far apart in time
  结论由于在重复测量资料中，同一受试者的不同观测值之间具有相关性特点，故对其指定协方差结构尤其重要。
• In addition , all the var methods focus on the central observations or , in other words , on returns under normal market conditions . however , var is a risk measure that relates solely to the tails of the distribution
  另外，所有的传统var估计方法都是集中在位于分布中部的观测值，即正常条件下的回报，但尾部才是var计算中所最关心的。
• 8 . a general estimator for adaptively robust filter is developed , which includes the estimators of classical kalman filter , adaptive kalman filter , robust filter , sequential least squares ( ls ) adjustment and robust sequential adjustment
  针对观测值粗差和载体机动误差，提出了抗差自适应kalman滤波的新算法，并对该算法作了进一步的改进。
• 1 . method that controls quality of field observation values of unbonded elastic wire resistance type meters is studied . methods that examine system error of different types in observation values are discussed
  主要研究内容如下： ( 1 )研究了差动电阻式仪器现场观测值的质量控制方法；探讨了对监测数据中不同类型的系统误差进行检验的控制图法和连检定法。
• Conclusions repetitive measure in analysis of qol can not only demonstrate the change in qol and its time trend , but also explain the degree of change with time for the qol in different groups by interaction meaning
  结论重复测量在生命质量的研究中不仅能够说明各观测值随时间的变化趋势，并且能通过交互作用的意义来说明分组因素的作用是否会随着时间发生变化。
• The flac - 3d calculated values are made contrast analysis with the finite element calculated values and observed values , and mechanism of deformation at the deep part of rock mass and the interface slip is deep into research in three gorges permanent shiplock
  将flac - 3d计算值、有限元计算值和观测值对比分析，深入研究三峡永久船闸深部岩体变形和局部位错的机理。
