查询词典 confidence coefficient

We use the Taylor series expansion method to get the second-order approximate expression of the confidence region of the parameters, and then according to the principle of minimizing the volume of the confidence region, this paper carries out experimental design for the regression model, and then fixes the point range in the domain of definition of design variable for the model function so as to select the designing point, which can minimize the volume of the confidence region.

文章首先计算指数族非线性模型的回归参数β在1-α置信水平下的置信域的体积，为了便于计算，需把置信域投影到切空间中去，投影后的置信域是一个椭球体，用Taylor展开方法对此椭球体的体积进行二阶近似，推出原参数置信域的体积的近似表达式，然后对回归模型进行试验设计，根据置信域体积最小准则，在模型函数的设计变量的定义域上确定点列，选取使置信域体积达到最小的设计点。

The moderate self-confidence situation is the good psychological performance, it will be able to urge the university student psychology the health development, nearly will produce the inner dynamics, will cause them positively displays, the optimistic point of view in the study and the life "outstanding" the self-confidence can cause the individual university student to have, the complacent point of view arrogantly, if they will come across the setback, not the ideal means will restore, then, once will have "is outstanding" the self-confidence university student to be able to give up oneself or fills to society's disaffection.

适度自信心情况是良好的心理表现，它将会促使大学生心理的健康发展，近而产生内部动力，使他们在学习和生活上表现出积极、乐观的心态。"优秀"自信心会使个别的大学生出现骄傲、自满的心态，如果他们遇到挫折，没有理想的办法来恢复，那么，曾拥有"优秀"自信心的大学生将会放弃自己或充满对社会的不满。

First of all, we introduce some interval methods and propose a new approach to find confidence interval for the slope in homoscedastic measurement error models. The performance of the interval estimation is compared in terms of both coverage probability and its diameter via simulation studies. Second, we suggest two approaches to estimate confidence intervals for the slope and joint confidence regions for both intercept and slope in heteroscedastic measurement error models. Application of these methods are illustrated with real data sets.

首先，当测量误差的变异是同质性时，我们对斜率项参数建构信赖区间，除了回顾已发表的方法外，也提出一个新的方法，建议的区间方法分别和已存在的方法做模拟比较，比较的标准建构在覆盖机率和平均长度上；另外，当测量误差的变异是异质性时，我们不仅对斜率项参数建构信赖区间提出新的方法，也对截距项参数和斜率项参数建构联合信赖区间。

Environmental test and life test were applied to the sensor, and the environmental confidence level and the one－ sided confidence lower limit of MTBF were estimated with the fiducial method, confidence interval method and Bayes method.

首先对这种传感器实施了环境试验与寿命试验，并用经典法、信赖法和贝叶斯法估计了环境可靠度及MTBF的单侧置信下限。

Because commercial banks have expected to prevent the losses at certain confidence level by using their own reserve for bad debts and capital at risk, commercial banks won't go bankrupt within certain confidence level. If the confidence level were a, the probability of bank failure is 1-a, so the recognition of deposit premium ratio should be performed based on 1-a of risk assets in commercial banks.

由于商业银行自身用损失准备金和风险资本来防范了一定置信水平内的损失，因此，在该置信水平内商业银行是不会破产的：如果一定置信水平为α，则银行破产的概率就为1—α，存款保险费率的确定就以商业银行风险资产的1—α倍为基础进行。

Assume β=1, and confidence level is 0.95, the length of normal confidence interval is compared to the length of shortest confidence interval, the results show: both absolute difference d and relative difference e are decreased by the increasing sample number n, when n≤9, e≥10%.

在假设参数β=1，置信水平为0.95的条件下，比较了常用置信区间与最短置信区间的长度，结果表明：两者长度的绝对差d和相对差e均随样本容量n的增大而减小，当n≤9时，e≥10%。

Not only in agriculture, forestry, animal husbandry and fishery, medicine and other pre-and benefit from the resilience of the industry in general inflation down, the financial and real estate funds fell sharply after重仓股after补跌recently emerged, which means that the market valuation of the new criteria are being re - the establishment of the Fund would need in the new game environment gradually reach consensus in order to allow the market to shake off the pattern of consolidation, re-restore confidence, but the economic fundamentals are not supporting the advent of this trend, the source said, in terms of market confidence, or from the capital side, the growth performance of listed companies, market confidence of view, do not have to do more to provide too many reasons.

不仅在农业，林业，畜牧业，渔业，医药和其他前和受益于该行业在一般的通货膨胀适应能力下降，金融和房地产基金重仓股大幅下跌后，最近出现了补跌，这意味着对正在重新评估市场的新标准-该基金的设立将需要在新的游戏环境，逐步达到共识，以使市场摆脱巩固格局，重新恢复信心，但经济基本面不支持这一趋势的到来，该人士表示，在对市场失去信心，或从资本方而言，上市公司，市场认为信心的增长表现，没有做更多的工作提供太多的理由。

Also, generalized confidence spheres of regression coefficient are proposed with the concept of generalized confidence region.

模拟结果显示，这种检验能很好的控制检验水平，并且有更高的检验功效。

How likely the interval is to contain the parameter is determined by the confidence level or confidence coefficient.

置信程度或置信系数决定了区间将在何种程度上涵括参数。

Based on the relationship between the risk-aversion coefficient and the confidence level in VaR, liquidity-adjusted VaR at any confidence level was obtained.

由于投资者风险偏好系数和VaR下的置信概率水平具有一一对应关系，可以通过最优路径集下执行成本的期望和标准差组合曲线来获得不同置信概率下，经过流动性调整后的VaR。

I'm not an actor. I'm a professor of paleontology.
