我们在生物数据统计分析中,经常会听到p-value,adjusted p-value,q-value以及False discovery rate(FDR)。比如最常见实验组和对照组的差异基因表达分析,除了获得一个p值(p-value),通常而言还会得到一个adjusted p-value或者FDR(false discovery rate)。那么他们之间到底有什么关系,为什么已经有了一个p-value来指征显...
总之，理解并正确使用这些指标，如p-value、adjusted p-value（q-value）和FDR，对于防止因多重检验导致的误导性结果至关重要。在进行大规模数据分析时，需要综合考虑这些指标，以确保科研结论的准确性和可靠性。
Adjusted-p-value Matlab code for algorithm performance comparison using the Friedman test and the Hommel procedure involves several steps. First, implement the Friedman test to determine if there are significant differences among the algorithms. Then, calculate the adjusted p-values using the Hommel ...
Collaborator kevinschaper commented Apr 26, 2024 I'm not sure if these belong all the way up on Association, or if they should be more applied to more specific associations Add p_value & adjusted_p_value slots to Association class 29533f7 kevinschaper requested a review from sierra-moxon...

terminology "q-value" for a quantity estimates his definition of FDR. He implemented q-value estimation procedures in an R package called qvalue.So, strictly speaking, the q-value and the FDR adjusted p-value are similar but not quite the same. However the terms ...
concept of an FDR adjusted p-value. The terminology used by the p.adjust() function and limma packages has lead people to refer to "BH adjusted p-values". The adjusted p-value definition that you give is essentially the same as
PD-L1表达阴性患者中, ctDNA-adjusted bTMB分组 和 治疗分组的PFS和OS的交互p value达到显著(OS:交互p value为0.010;PFS:交互p value为0.001),且高ctDNA-adjusted bTMB患者中阿替丽珠单抗治疗组的中位OS(16.3个月 vs 8.3个月,HR...

Here, in a study of 6,896 individuals evaluated from 11 cohort studies from six countries, we determined the positive and negative predictive value of five plasma biomarkers for amyloid-β pathology in cognitively impaired individuals in relation to clinical pretest probability. We observed that p-...
