q-value是FDR的另一种表达方式,通过优化p值分布来计算,可以提供更准确的假阳性和假阴性预测。以代谢组学为例,q-value分析可以更准确地估计在大量假设检验中,哪些显著结果可能是误报。表1中显示,化合物A的p值虽然小,但q值较大,提示其显著性有较高的假阳性的可能性。在选择阈值时,应考虑q值而...
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...
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 ...
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 the BH adjusted p-value, except that you omitted the last...
如果将固定 p 值用于多重比较,则全族误差率会随每个附加比较而增加。调整的 p 值还表示拒绝特定原假设时的最小全族误差率。 进行多重比较时考虑全族误差率很重要,因为对于一系列比较而言,发生类型 I 错误的几率比单独进行任何一个单个比较的误差率都要高。 调整p 值的示例 假设您比较了...
Calculate the adjusted p-value for each p-value using the formula: Adjusted p-value padjusted(i)=min{1,minj≥i{mp(j)j}}p(i)adjusted=min{1,minj≥i{mp(j)j}} where: padjusted(i)p(i)adjusted represents the adjusted p-value for the i-th ranked p-value. p(j)p(j) represents ...
