查询词典 statistic decision problem

Firstly, the system is divided into four sub systems: Chinese characters recognition system, character recognition system, recognition system including characters and digits, and digital recognition system; Secondly, the statistic information about left scan line free length of every character is used as a group feature of car plate, which will accomplish the recognition together with statistic template by weighted sum.

首先将车牌字符识别分成四个子识别系统——汉字识别系统、字母识别系统、字母和数字混和识别系统，以及数字识别系统；然后选择各字符的左扫描线空程长度统计信息作为车牌字符的一组特征，与统计模板进行加权组合，来共同完成车牌字符的识别工作。

A statistic is sufficient for inference about q if and only if the values of any sample from that distribution give no more information about q than does the value of the statistic on that sample.

但莫明其妙的是，在很多情况下，这么多因素的信息居然浓缩在"星座"这一个信息里。

In statistics, a statistic is sufficient for the parameter θ, which indexes the distribution family of the data, precisely when the data's conditional probability distribution, given the statistic's value, no longer depends on θ.

统计量是样本的不带任何未知量的函数，一般而言，统计量所包含的信息比样本要少，但可能这些漏掉的信息是无关紧要的。

Each t statistic has a t distribution, and each F statistic has an F distribution.

此时t统计量服从t分布，而F统计量服从F分布。

Thirdly, we discussed how to decide whether the process is in control and if not, what shall we do to remove the signals. In this part, there are two aspects: T~2 statistic with unknown parameters and T~2 statistic with known parameters.

在此基础上，对如何通过历史数据建立稳态进行研究，其中的主要内容分为已知参数的情况下的异常值判异，未知参数情况下的异常值判异。

Indicates the probability of your calculated F or t statistic being as large as it is by chance. A low p value is good and means that the F statistic is not coincidental and, therefore, is significant.

J4 ？； 2 u/ X5 Y9 ' m L 表示计算F的可能性或者统计的数据越来越大。P值越低表示越好，并意味着F统计的可能性越高，因此更有意义。

The results showed: there was not statistic difference of recurrence rate between ER positive and negative groups. There wasn't either statistic difference of recurrence rate between AR positive and negative groups.

结果提示膀胱癌复发率随雌激素受体表达增多有下降趋势，但无统计学显著差异；雄激素受体表达阳性与否亦与肿瘤复发率无关。

The multi-dimensional signals measured by sensors with a machine working under normal condition or fault condition, can be used to build Q statistic and T^2 statistic respectively to detect the state of the machine. Meanwhile, the feature vector is constructed by the Q value and the T^2 value, the geometrical distance between the normal feature vector and the feature vector H when the machine goes wrong is used to realize the fault location. The results show that the method is feasible.

利用多个传感器测量的异步电机多维信号参量，构建电机在正常工作和发生故障时的Q统计和T^2统计，以实现电机的状态检测；利用Q统计和T^2统计值构建电机的状态特征向量，通过比较度量当前电机的特征向量与电机发生故障时的特征向量H的几何距离来实现电机故障的定位与分离实验证明，该方法可以有效地实现故障的诊断与分离。

To study local influence of the data cases on the Score statistic for the test of varying dispersion in the nonlinear model of simplex distribution, this paper develops the local influence on the score test statistic under perturbation in the response variable and explanatory variables based on gradient method.

为了研究数据对于单形分布非线性模型变离差检验的Score统计量的局部影响，该文利用梯度方法分别研究了因变量及自变量的微小扰动对于该模型的Score检验统计量的局部影响，相应得到了度量最大局部影响的诊断统计量。

In analysis of these data, we proceed an descriptive statistic analysis by using SAS statistic software tool to analyze representative of samples, chi-square test of independence, factor analysis and the model test.

在资料分析方面，除了对样本资料进行叙述性统计分析外，并以SAS统计软体进行样本资料的代表性分析、卡方独立性检定、因素分析与模式的校估检定工作。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
