查询词典 classification statistic

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。

When we compute the statistic for a particular sample, we obtain an outcome of the test statistic.

当我们用某一特定样本计算此统计量时，我们得到这个检验统计量的一个实现值。

Test Statistic -- The test statistic is the outcome of your statistical test and is calculated differently for each test.

检验统计量--是统计检验计算出来的结果，依照每个检验而不同。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.
