Some of the researchers used statistics and explain the findings effectively. In other hand most of the researchers are using statistical tools without understanding of statistical technicality and thoughts. Concept of normality is the most important part of statistical techniques. The assumption of ...
- 《Computational Statistics & Data Analysis》 被引量: 69发表: 2006年 Testing the assumption of multivariate normality Methods of assessing the degree to which multivariate data deviate from multinormality are discussed. The best known of these methods, Mardia's tests of multivariate skewness and ...
Work will now begin to test the hypothesis in rats.在老鼠身上验证这一假设的工作现在要开始了。The statistics to prove or disprove his hypothesis will take years to collect.要花数年来收集证实或推翻他的假设的数据。2.assumption 例句: People tend to make assumptions about you when you have a ...
In addition, we need to determine certain properties of the object at the intersection point, such as a surface normal or its material. Most ray tracers also have some facility for testing the intersection of a ray with multiple objects, typically returning the closest intersection along the ray...
Distributions of tests statistics are investigated under violation of assumptions that samples belong to the normal law. Distributions and power of nonparametric tests for dispersion characteristics homogeneity are researched (Ansari-Bradley's, Mood's, Siegel-Tukey's tests). The comparative analysis of ...

465] Pierre Duhem argues that the “main criterion for scientific evidence” is for a mathematical law to be in “accordance with experience” [Duhem, 1991, p. 22]. In line with this approach, Michael Redhead stresses that “testing of theories” means to make “predictions [based on ...
