平均差

Various methods such as the relationship of area, and the distance of the triangle to the centralness of three dots, the distance from the interior point, exterior point, the barycenter to the vertices of triangle, and the standard error and differences average obtained from three dots were determined with a dynamic geometry software GSP, and a statistic method was used to find a least error way to determine the centralness of three dots on a plane.

本研究是以平面上三点所构成的三角形之三顶点做讨论，分别以三角形的面积、周长，内心、外心和重心至三顶点距离，三点的标准差及平均差的概念，做为不同的判别方式，并以动态几何画板 GSP模拟不同的判断方法作为研究，再利用统计学上的方法，找出哪一种定义方式为最适合、误差最少的判断方法。

另外，为了考察图像的空域信息，本文提出了两个统计特征：局部匹配度特征和局部最大平均差分特征。

Specifically, it is necessary to calculate accurate estimates for the mean and standard deviation of demand during lead time.

O 特别是要对在交货前置期内需求的平均差和标准差进行精确的计算评估。

With the evaluation, each group measuring value is considered as a single subsystem, and the minmax-difference, mean difference and the mean square value of each group are calculated. Then, the ratio of the mean difference to the measurement mean value is defined as the system-relatively error of subsystem and the ratio of the minmax difference to the measurement mean value is defined as the accidence-relatively error of the subsystem.

以每组为一个子系统，分别计算出每组的极差、平均差和标准差，然后定义平均差和测量平均值的比值为子系统的系统相对误差，定义极差和测量平均值的比值为子系统的偶然相对误差。

It was found that both the root mean square error and the mean error were minimal when using the neural network and fuzzy controller.

在临床试验部分，本研究针对四位受测者进行不同控制器的控制品质比较，结果发现以类神经网路加上模糊控制器的控制方法，其均方根误差及平均差皆为最小。

Using Lab VIEW, we construct a well man-machine conversation and analyze the data by signal processing method.20 volunteers are examined by the prototype instrument and the Synergy electromyograph (Dantec Ltd. Denmark).

我们选取20名健康志愿者分别在南方医院的肌电—诱发电位仪和实验样机上作测试，采用标准差—平均差法等方法验证了仪器的一致性。

We used standardised mean differences with 95% confidence intervals to pool study results where possible.

可能的情况下，我们使用95％可信区间的标准平均差来合并研究结果。

Significantly lower scores were found with PSC opacities, with an overall adjusted mean difference of 6 points (95% CI: 3.3-8.8) for the composite score.

明显的低分数与后囊下白内障混浊相关，综合评分中的所有校正平均差为6分（95%置信区间3.3-8.8）。

First, calculates the fast moving average (usually 12 days) and slow moving average (usually 26 days) by exponential calculation method; second, make fast line value minus slow line value to gain the difference of relative distance. In order to make the trend signals more clear and less influence exerted by of excessive price fluctuation, the difference should be smoothly calculated (general elect 9 days) to get average of difference value. Chart the difference and its average in a coordinate with time for horizontal axis and MACD for vertical axis. Then we can apply the identical, contrary or cross signals through observing their direction, relative and absolute positions.

它首先以指数平滑计算法计算出快速移动平均线（一般选12日）慢速移动平均线（一般选26日），再以快速线数值减慢速线数值即得到快慢线相对距离的差离值，为使趋势信号更明显并且不受股价过分波动的影响，对差离值也进行平滑计算（一般选9日），得到差离值的平均值，把差离值和差离平均值画在以时间为横轴，以MACD为纵轴的坐标上，通过观察差离值和差离平均值的方向、绝对位置和相对位置关系，把它们的同向、异向和交叉现象作为买卖信号的提示。
