我得到这个数据
CellTypeI CellTypeII CellTypeIII
Hypermethylated 5400 1600 500
Hypomethylated 450 1500 150
用Fisher exact test or chisq test只能说明methyaltion和CellType是相关的。
但是不能表明CellType中的哪种enriched with hyper or hypo-methylation。
显然,CellTypeI中Hypermethylated的数目比较多,要用什么test来说明
CellTypeI is significantly enriched with Hypermethylation。
另外 Is CellTypeII enriched with Hypomethylation?
Thanks!!!

我觉得这个数据本身就够了。画个diagram不会有疑问的,弄出个pvalue来是画蛇添
足。

如果不作test,怎么回答

permutation test or hypergeometric test for each row?

How about one-sided fisher exact test

Fisher's test is only for binary 2x2 table, use chisq test to test
association between CellType and methylation.
WITHIN each cell type, use binomial test to test if the cell type is
enriched with hypermethylation. This can be done by either calling test
procedures or by permutation. For example, in R

The difference is huge, and you don't necessarily need an 'official' test to
prove it. Here is some brutal force method for a quick answer:
Step 1: Calculate the percentage of Hypermethylated cells for each type.
This is your p-hat.
Step 2: Calculate the standard deviation for sample mean (your p-hat for
each cell type). Too much hassle to type in a formula here, but you may
check out this link:
http://en.wikipedia.org/wiki/Binomial_proportion_confidence_int
Step 3: Calculate the standard error and then the 95% confidence interval
for each p-hat. If they don't overlap, then you can claim significance.
Copy & paste below output back to excel for better layout. Try exercise the
calculation by yourself. Enjoy.

其实iTunes管理歌曲是很方便的。但前提是你歌曲的各种tag信息要全。
