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...
虽然p-value直观地表示在假设H0（不存在差异）为真时，观察到数据的概率，但它可能受到多重假设检验的影响，导致假阳性结果。为了解决这个问题，我们引入了调整后的p-value（如adjusted p-value或q-value）和FDR，它们旨在控制假发现的数量。调整后的p-value，如q-value，是FDR的计算结果，它考虑了所有...
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...

p-value:表示某个基因在分组之间的表达是否差异显著,一般认为p-value<0.05为显著。adjusted p-value:即经过统计学方法校正后的p-value,由于统计学上常用的校正方法包括“BH”、“FDR”等,所以在一些文章中,我们也会看到筛选差异基因的阈值是FDR<0.05。p值越小差异越显著,但直接用adjusted p-value画图的话点会...
