进行Hypothesis Testing 有两种方法,一种是Critical value 方法,另一种是P-value approach. 下面,我来分别介绍这两种方法。 Hypothesis Testing (Critical value approach) critical value方法比较observed test statistic和critical value,如果test statistic比critical value更加极端,那么null hypothesis is rejected. 如果tes...
The t-table indicates that the critical values for our test are -2.086 and +2.086. Use both the positive and negative values for a two-sided test. Your results are statistically significant if your t-value is less than the negative value or greater than the positive value. The graph below...

F critical value is a value at which the threshold probability α of type-I error (reject a true null hypothesis mistakenly). The f statistics is the value that follows the f-distribution table. Here are a few tests that help to calculate the f values. ...
-n = 10 < 30, 所以需要用t-test, t-table, t-score -根据 CI= 0.99, 查表,df(degree of freedom) = 10-1=9, alpha = 0.01, t-value = 2.8214 -此时曲线下方,左边是 -2.8214, 右边是 2.8214 -根据此题,小于,那么就需要使用 -2.8214, 即 Critical Value = -2.8214 ...
Question assertions made by the author. Don't accept what is written at face value(完全地, 以面值/表象). Before accepting what is written, be certain that the author provides sufficient support for any assertions made. Look for facts, examples, and statistics that provide support. Also, look...
According to incomplete statistics, approximately 10,000 environmental NGOs specialize in environmental issues or have significant influence in the environmental field. Some well-known environmental NGOs already have strong social influence and can even affect the formulation of environmental policies and ...

Peptides were filtered on length (between 6 and 50 amino acids), and charge state (+2, +3, and +4), and a maximum valid expectation value (e-value) of 0.186. The following database search engines were used for the pipeline comparison: (i) MaxQuant87 (including the search engine ...
1 and Supplementary Table 3). Absolute values for metrics are log scaled. Lines indicate different subsets of genomes analyzed, and the value of the GSAs indicates the upper bound for a metric. The metrics are shown for both unique and common strain genomes. g, Genome recovery fraction versus...
