19.10.2Set significance level As with our other hypothesis tests, our significance levelαis set using your comfort level of making a Type I error and field convention, with a default ofα=0.05. In our example, we will work with the defaultα=0.05. ...
The HER2gene expression levelis of clinical significance in correlating with patient prognosis in breast cancer[1]. Higher levels are correlated with poorer prognosis yet successful treatment of breast cancer with the drug Herceptin® is positively correlated with HER2 overexpression, and thus its accu...
The procedures to abstract the significance of a factor from objective information are discussed in detail. An example is presented to show the application of the proposed method. 关键词: fuzzy cluster analysis fuzzy comprehensive evaluation significance ordering rough sets ...
Red:characterizing those items: i) whose size was lower than 4, thus preventing the evaluation of normal distribution approximation, as detailed above; ii) items for which we rejected the null hypothesis of bell-shaped distribution at the 1% level of significance (p-value < 0.01), therefor...
b, scPoli reference mapping: the model weights are frozen (in gray) and a new set of condition embeddings are added to the model. Cell type labels are transferred from the closest prototype in the latent space. Example of a standard workflow using scPoli on multiple pancreas datasets. c,d...

. The categorical variables were tabulated according to the exposure group and analyzed using a Chi2 or Fisher test. For all statistical tests will a null hypothesis, a significance level of 0.05 and a confidence level of 95% (95% CI) were established. A simple regression model was ...
1、Alpha Level (Significance Level,显著水平): What is it? 显著性水平α是指当零假设是正确的,但做出了错误决策的概率(即一类错误的概率)。Alpha水平(有时称为“显著性水平”)用于假设测试。通常,这些测试的alpha值为0.05(5%),但是其他常用的值是0.01和0.10。
