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.
