29 Mar 2014 gmregress Geometric Mean Regression (Reduced Major Axis Regression). Author: Antonio Trujillo-Ortiz Antonio Trujillo-Ortiz

The slope sign bug was efficiently corrected thanks to the valuable suggestions given by Holger Goerlitz and Joel E. Cohen. Yes, a negative slope are always negative!

Hi John,

Thanks for your broad and useful mathematical fundament comment. I'll review the file script and take into account those in order to improve it.

04 Jul 2013 Mutivariate normality omnibus test Multivariate omnibus test as proposed by Doornik and Hansen (1994). Author: Norlianida Abdullah Antonio Trujillo-Ortiz

Hi Norlianida. This m-file was already developed and published since 6 years in this forum [http://www.mathworks.com/matlabcentral/fileexchange/17530-dorhanomunortest]. I see it is pretty much a copy of it. The help section with a little modification. In particular, I think you should do a very thorough search, especially in this forum, in any previous coding of any procedure of interest. I think still there are many, many statistical procedures that require and are waiting to be coded and developed into Matlab.

Yours,
Prof. Antonio Trujillo-Ortiz

Dear Michael,
Thanks for your interest of this m-file. As you know, we only generated the Matlab computational algorithm from the original published paper. If you have any mathematical or statistical fundamentals inquiry you must refer to the author(s). I give you the Dr. Norbert Henze's email address
henze@stoch.uni-karlsruhe.de
and/or
N.Henze@math.uni-karlsruhe.de

However, we don't need the lognormal cdf (logncdf) neither the mean and variance of the lognormal distribution (longnstat) functions. For the used mean (mu) and variance (si2), which are the Henze-Zirkler mean and variance, must, as the author establish, to be converted to the lognormal Henze-Zirkler mean and variance. As you can see, using the provied Iris data example. The mean(mu)=0.7635 and variance(si2)=0.0112. With a Henze-Zirkler lognormal mean: -0.279408 and Henze-Zirkler lognormal variance: 0.1379069. But, if you try to use te mu and si2 values by the longnstat function, you get the incorrect lognormal values of 2.1459 and 5.7768e-004, respecively.

Yours,

Prof. Antonio Trujillo-Ortiz

Hi zapp,

I think your rate is so rigourous, and twice (only one should be fine)...!!!

Recall that I'm not the author of the statistical procedure, but only of the Matlab function. So, I suggest you could contact the authors and statistically establish your point of views. Also it could be better you publish your deep statistical rejection.

Finally, are you sure what the procedure statistically does?

Yours,

Antonio Trujillo-Ortiz

We thank Alex Karandreas from the Department of Acoustics, Aalborg University, Denmark, for encourage us to include a graeco-latin example. This has been done.
