【通俗理解】显著性检验,T-test,P-value 备注: 源:https://www.cnblogs.com/hdu-zsk/p/6293721.html <https://www.cnblogs.com/hdu-zsk/p/6293721.html> 显著性检验,判定实验结果是否由随机误差导致的。举例很好,很清楚 虽然样本中,均值苏州销售额大于郑州,但T-test发现这是随机导致的,P>0.05,当样本量足...
The p-value is a measure of the statistical significance of the expression difference and is based on anegative binomial test. The p-value reported here has been adjusted for multiple testing via theBenjamini-Hochberg procedure. In this table you can click on a column to sort by that value....

差异的显著性(P-value) 这就是统计学的范畴了,显著性就是根据假设检验算出来的。 假设检验首先必须要有假设,我们假设A和B的表达没有差异(H0,零假设),然后基于此假设,通过t test(以RT-PCR为例)算出我们观测到的A和B出现的概率,就得到了P-value,如果P-value<0.05,那么说明小概率事件出现了,我们应该拒绝零假...

Protein expression in Myc3-iSH2-p110-expressing cell lysates was normalized to the wild-type protein, which was assigned a value of 1. The amount of Myc3-iSH2-p110β bound to GST-Rab5 fusion proteins in each pull-down experiment was normalized to wild-type Rab5-GTPγS (100%). Data...
