If your interim analysis is futility analysis, by definition, you may
wrongly terminate the experiment when your H1 is true. This increases the
type II error, which lowers the power. But if your trial designed correctly,
this can be adjusted (for example, increase sample size). For example, beta

If your interim analysis is efficacy analysis, you'll have more chances to

为这两个我会，就是不知道用处广不广。用在什么领域。本人没作过data scientist.
本来以为bayesian analysis可以用在online learning的领域，后来发现如果用

发帖数: 26311 | 5 你们说的survival analysis就是
stochastic process/reliability analysis的？
没做过marketing，
不过所有survival analysis的应用应该都差不多--
user attrition是一个event，
用一般的classification方法可以用来预测event occurrence within a certain
width of period
用survival就可以用来预测when the event will occur
logistic regression可以视为Cox model with exact/discrete time treatment of
tied events的特殊形式 |

发帖数: 1312 | 30 你做DE analysis的时候是用什么package？
如果是DESeq2或者EdgeR，默认不需要考虑gene length。因为默认是比较相对表达变化
，不依赖于gene length。control和treatment或者不同tissue的reference都是一样的
，gene length也都是一样的，所以不依赖于gene length。除非你用不同的reference。
然后GO analysis input 是DE analysis output，只分析那些DE gene，也和gene
length无关。
写到这里我又看了一下你的问题，突然明白了我以上回答答非所问。。。
你只看了某“一个”TF的binding site，然后把这一个list，没有做任何DE，直接放到
GO里了吗？如果只有一个组织，没有做DE，我不确定这样做是否正确。
如果是同一个TF，但是有两个或更多的不同组织，做了DE之后，然后把DE list放到GO
里，应该没问题，也不需要考虑gene length。理由同上。 |
