大家好！ 求不同变量频数的描述性统计量，range,mean等，（我想对这些频数标准化处理后在计算）它的原始数据是输入直接从WSM，dispersion plot中的百分比的数据吗？我发现用相对频数和绝对频数得出的描述性统计量的结果不一样啊。要进一步作因子分析，是不是还使用这些数据呢？谢谢！

Use the normalised frequencies (per 1000 words from the Wordsmith dispersion plot).

But I think the questions have asked so far in other threads indicate that you need to have more background knowledge of MF/MD to undertake the research you are doing. I understand it is hard to get Biber's 1988 book. But here are some sources available-

1) An overview of Biber 1988 approach: http://forum.corpus4u.org/upload/forum/2006040723233361.pdf
Source: Biber, D. 1995. ‘On the role of computational, statistical, and interpretive techniques in multi-dimensional analysis of register variation: A reply to Watson’. Text 15/3: 341-370.

2) Tribbble 1999 Lancaster PhD thesis: chapter 4

Here is the bundle I have downloaded:

many thanks,Dr.Xiao! all your instructions and materials you offered me are really helpful for my study in corpus linguistics, especially for my thesis proposal preparation! thank you again![emm1][emm1]
