True or False: The null hypothesis is rejected if the p-value (i.e. the probability of getting a test statistic at least as extreme as the observed value) is greater than the significance level. If the test statistic for a difference o...
The asymptotic distribution of the test statistic, and the p-value function are discussed. The application of proposed method is shown using a real-life data set. 展开 关键词: rank test statistic differential genes power efficient DOI: 10.1177/0962280211434428 ...
First, a P-value only shows the probability of getting a result assuming that the null hypothesis is true and does not reflect the probability of ... J Jakobsen,C Gluud,P Winkel,... - 《Bmc Medical Research Methodology》 被引量: 92发表: 2014年 ...
The number of clusters can be chosen as the smallest value of k such that the gap statistic is within one standard deviation of the gap at k + 1. This means that the clustering structure is far away from the random uniform distribution of points (Tibshirani et al., 2001). Our ...
The DBLP stands out from other datasets in the number of articles it contains. Yet, further research into dataset characteristics is needed to explain the behavioral deviations. Descriptive statistic. The topic specificity is a descriptive statistic rather than a performance metric; the ‘optimal’ ...
This measure was quantified by calculating the AUROC, which is equal to the c statistic (concordance). The AUROC value gave the probability that a randomly selected patient who has familial hypercholesterolaemia has a higher probability score than a patient who does not have familial hyper...
The ranks are converted into p-values (P1 and P2) using the R-test which is discussed later. The p-values P1 and P2 are combined using Fisher's omnibus procedure to obtain the unified p-value (U). Figure 1 Unified Framework to find DEGs from Microarray Data. Full size image MathML ...
The Finder searches for high-p T segments in each of the superlayers, and the Linker searches for high-p T track candidates by combining segments from at least three (out of four possible) segments. Both stages use pattern matching to accomplish their tasks. 5.2.2 ATLAS Fast Tracker The...
[12] proposed the gap statistic that measures the difference between within-cluster dispersion and its expected value under the null hypothesis. The k that maximizes the difference is selected. Since the gap statistic uses within-cluster sum of squares around the cluster means to evaluate the ...
The maximum of the cumulative sum, from partial sum 10 (“S10”), is seven. The test statistic is the absolute value of the maximum cumulative sum divided by the square root of length of the pitch vector. The test-statistic gives us an idea if the maximum cumulative sum is unlikely to...
