Its very Good.

Extremely helpful. It's hard to find programs that will perform Hotelling's T2 test, specially in an easy way. Well commented, clear results.

My Dear Ji Cling,
 
Regularly I visit this FEX site in which excellent contributions for the fast solution of diverse types of problems in several disciplines have been given. The accusation that you are causing is very delicate. I do not know you. Neither the authors. We known them only by the references given in their author page. Only what I believe is in the quality of ethics of each one of them and ours. We are serious people dedicated to our work in the most diverse specialties. To be certain what you say. Then not alone this author does cheating but also all the others. Even you, that in principle, I think you are not signing with your true name. Finally, or really the community are honestly dawnloaded the m-files or finally someone are doing a very bad play. This because there exists a lack of control on this.

Best Wishes.

Mike

Oh, little frog.

I just checked one-sample (T2Hot1.m) using an example 13.3 from Armitage et al. Statistical Methods in Medical Research, ed. 4. The results are nearly the same, which is very good:
From book: T2=7.439, F=1.24 and P=0.39
From T2Hot1.m: T2=7.4315, F=1.2386 and P=0.3873

Very good job!

Actually, yes. It's odd that Mathwork implemented one-way MANOVA ('manova1.m') without more simpler statistic such as Hotelling's T^2.

very good and easy to use. It has alot of examples which explain it very well

On keywords last word must to be: samples.
22 Apr 2003

It was added an appropriate format to cite this file.
12 May 2003

Last keyword was type corrected (sampl=samples.)
19 May 2004

The file was improved simplifying the input arguments as the samples-size vector request, now automatically estimated.
15 Apr 2005

Text was improved.
