On the assumption of the unification of two stock markets, we apply several commonly used statistical methods, such as factor analysis, clustering analysis, correlation analysis, to build an effective model by which an objective stock sample can be obtained for computing index. Meanwhile, the inform...
参考作文: Some bookworms in my dormitory often spend hours reading their “Bible”, Practical English Grammar, and do a lot of exercises in that book ,but I don't care about it at all. My assumption is since I have never learned Chinese grammar, what's the sense of learning English ...
No evidence was found for a violation of the equal-environment assumption regarding monozygotic and dizygotic twin pairs. CONCLUSIONS: Familial factors, which are at least partly genetic, influence sexual orientation. The results of these analyses should be interpreted in the context of low statistical...
Research and development related to new products based on medicinal plants have increased mainly due to the widespread assumption that natural products are harmless [5]. However, plants are not completely free of adulteration by synthetic materials that can cause contamination [1]. Due to the use ...
In this two-sample MR study, we expanded the analysis to include seven other sex steroid hormones as well as investigating the effect of the hormones on subtype-specific BC risk (luminal A-like BC, luminal B-like BC, luminal B/HER2-negative-like BC, HER2-enriched-like BC, TNBC and BRCA...
Assumption 1. There exist constants 𝑎>1 and C such that 𝜆𝑘−𝜆𝑘+1≥𝐶𝑘−𝑎−1 for 𝑘≥1 and 𝐶−1𝑘−𝑎≤𝜆𝑘≤𝐶𝑘−𝑎. Assumption 2. ∫𝑙𝐸𝑋4<∞,∫𝑙𝐸𝑌4<∞. Assumption 3. 𝜏=lim𝑛→∞𝑛1𝑛,0<𝜏<1. Assumption ...
When this assumption of the χ2 test is not satisfied, the exact conditional approach is the alternative that should be used to guarantee the type I error rate. The exact conditional approach is widely available in the majority of statistical software (SAS, R, StatXact, Stata, SPSS, etc.)...
The analysis is based on the premise that the magnitude of the true treatment effect is unrelated to design features of the study, in particular sample size. This assumption permits an analysis based only on published studies. Three primary endpoints are examined: overall patient survival, disease...
If we can accept the assumption about the repeatability of the experiments, it is safe to measure sample statistics to describe the variables based on the available data. To understand where on the numeric scale the values are located, one can estimate the central tendency of the distribution, ...
