查询词典 independence test

Another work of this paper is to study the continuous design of Test Automation. Common aspects of continuous design include the performance and maintainability of test automation system itself, the independence of test execution, and the analyzability of test result. This paper gives the concrete resolution of above four aspects, and also proposes other aspects need to be considered in continuous design, such as extendibility in future and capability to multi-product and multi-edition.

In statistical analysis of ordinal data, we usually build up linear-by-linear association model and meet a trouble of choice of scores. Graubards et a1 (1987) proposed several methods for score choice in independence test in ordinal 2×κ contingency tables: equally spaced scores, midpoint scores and midrank scores. He also pointed out that the result of independence test may be different for the different choice of scores according to the same association model. Agresti et a1 (1987) treated the score vector in row effects and column effects model for two-way contingency tables as parameters and derived the necessary and sufficient condition of the solution under monotone order restriction by Kuhn- Tucker conditions.

在有序数据的统计分析中，通常要建立线线相关模型，其中得分的选取是一个棘手的问题，Graubard et a1（1987）给出了有序2×κ列联表中独立性检验的几种得分选取方法：等距离得分，中点得分和midrank得分等，同时指出，对于同一个相关模型，独立性的检验会由于得分选取的不同而得到不同的结论，Agresti et al（1987）把二维列联表中的行效应和列效应模型中的得分向量作为参数，在满足递增的序关系情况下，利用Kuhn-Tucker条件给出了解的充要条件。

At first, the wind tunnel test and test data process of this study are introduced in detail. A method to calculate expected extreme values of time series with a long time interval is then proposed with its sub-sections based on the classical Gumbel theory for extreme values and the independence of observed extreme values. At last, the extreme values of the wind pressure coefficients of the present wind tunnel test are calculated with the proposed method and methods used widely at present, such as peak factor method, improved peak factor method and Sadek-Simiu method.
