在统计语言表达上，如果p值小于0.01，则称作0.01水平显著，例如，研究人员分析X对Y是否存在影响关系时，如果X对应的p值为0.00（由于小数位精度要求，展示为0.00），则说明X对Y存在影响关系这件事至少有99％的把握，统计语言描述为X在0.01水平上呈现显著性。

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来指征显著性，还要有一个adjusted p-value或者FDR（false discovery ...
