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

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

22 Feb 2013 qtukey Finds the Tukey's q studentized range critical value. Author: Antonio Trujillo-Ortiz Deb, Sav

The last if condition, return values only for v<120. For v> it returns errors!!

22 Feb 2013 qtukey Finds the Tukey's q studentized range critical value. Author: Antonio Trujillo-Ortiz Deb, Sav

Is there a better mode to obtain the q-vaue?
Has someone already converted Fortran routines prtrng() and qrtrng to m files?

Other solution?

Thanks

30 Jan 2013 nstir2k Stirling number(s) of the second kind. Author: Antonio Trujillo-Ortiz Dernoncourt, Franck

nstir2k(100 , 100) = -1.7403e+37
Should be equal to 1.

12 Jan 2013 sphertest File gives several sphericity tests as Bartlett and Mauchly to choose. Author: Antonio Trujillo-Ortiz sharika

As per the formula given in this link

http://www.originlab.com/pdfs/nagcl09/manual/pdf/rmanova/Repeated_Measures_ANOVA.pdf

all calculations require p = degrees of freedom of the factor rather than the levels of the factor.
