Several weeks ago, I posted a request for some statistical methods to
analyze matrices derived from some copora of written English by the native
speakers and the Chinese EFL learners. So far, I have received only 2
responses that offered some help.
 
1. alicesun at garnet.berkeley.edu :
There is another improved and better program coming out: STATISTICA. It has
the function you specified: multiple regression, general non-linear analysis,
stepwise discriminant analysis, log-linear, ANOVA, and so on. If you can get
on World Wide Web, their address is: http://www.statsoftinc.com. Or you can
give my your mailing address so that I can copy the brief intro to the
product, and you can have a look.
The company's name and phone/fax numbers:
 
StatSoft
2325 E. 13th St.
Tulsa, OK 74104
USA
Phone: 918-583-4149
Fax:     918-583-4376
 
It has offices in London, Paris, ... and Taiwan. The phone number for the
Taiwan representatives:
Intelligent Integration Corp: 2-759-1791, fax: 2-759-1790
 
I think that you can contact the company directly.
 
2. Prof. Gui Shichun from my own university (email:
itscgui at letterbox.scut.edu.cn) suggested that we use entropy-based
redundancy scores. The formula of entropy can be found in DATA, MODELS AND
STATISTICAL ANALYSIS by R.A.Cooper & A.J.Weekes, p.351, and the redundancy
score R is obtained by the formula
 
	R=H/ln(N)
 
where H is the entropy, N is the number of cases.
 
We found some encouraging preliminary results: a)Both cluster analysis and
redundancy scores show that the use of certain tag-pairs distinguish the
Chinese EFL learners from the native English speakers. The frequency of
these tag-pairs often reflects the differences between Chinese and English.
b) There is strong relationship of linear regression between the non-zero
frequency scores and the sample sizes.
