查询词典 weighted sampling

Typically, stockmarket measures are based on the market value of the constituent businesses; if company A is priced at $100m and company B at $50m, then the index will be weighted two-thirds/one-third in favour of the former.

典型地，股票市场的测度基于其所包含的企业的市场价值；如果 A 公司的定价为100万美元， B 公司被定价为50万美元，那么就前一个公司而言，在指数的权重为2/3比1/3。

Based on spatial contiguity and pixel comparability, a method was proposed which combined microscanning with weighted interpolation technique.

从空间邻近度和像素相似性角度出发，提出了微扫描和基于梯度特征加权插值技术相结合的方法。

At this in, we prove theorem of the modulus of continuity of levy under the condition of weighted sum that averagesinterval segments about normal wiener process, discuss that define in chapter 2 under of the Wiener process Be adding the power line to combine under of increase quantity have much small.

在这一章中，我们证明了关于标准Wiener过程的等间距分段加权和的Lévy连续模定理，讨论了在第二章中定义下的Wiener过程在加权线性组合下的增量有多小。

And then the approach is extended to continuous random variable. The optimal rule of general group decision-making is drawn by the new approach, which turns out to be a generalized weighted majority rule. The weight allocated to a decision-maker should be equal to the information quantity he provides.

鉴于Boltzmann—Shannon熵难以直接用来度量群体决策中信息的变动情况，我们提出了一种对离散随机变量的新的信息度量方法，证明了该信息函数仍然满足等状态时信息量最小这一性质；随后将其推广到了连续随机变量。

Methods According to the weekly influenzalike illness consultation rate of fourteen sentinel hospitals in Guangdong province from 2004 to 2006,the surveillance data of 2007 were fitted into models for early warning of inflecenza with three methods including control chart method,historical limit method and exponentially weighted moving average method.

采用2004～2006年14所哨点医院门诊每周就诊的流感样病例占门诊病例总数百分比数据，使用控制图法、历史限法和指数加权移动平均法，对2007年的流感样病例就诊百分比数据进行拟合，分析早期预警的效果。

But in our method, the reference function value of the iteration point is defined by a special weighted average, i.e., a convex combination of all previous function values.

而在此算法中，迭代点的参考函数值为一特殊的加权平均值，即前面所有点函数值的凸组合。

The spectral data were analyzed by weighted correlation. Pearson's R and Δ R (defined as the absolute value of the difference between Pearson's R and its mirror image in the correlation table) were calculated and used for assessing the spectral similarity between the drugs.

利用加权相关分析对以上光谱数据进行分析，得到各产品之间的Pearson′s R和ΔR(Pearson′s R 与其镜像位置值的绝对差值)，并以此进行各产品的光谱相似性比较。

In order to improve the robustness of image matching betwe en infrared images and visible images, a novel weighted cross correlation algorithm based on structure tensor was presented.

为了提高红外图像和可见光图像匹配的鲁棒性，提出一种新的基于结构张量的加权互相关算法。
