Dear Daniel As Rene mentioned, I am currently working on a (limited) statistics package, which implements some functions of the statistics software R (http://cran.r-project.org/) as C++ classes for use from within ROOT. Currently, I have wrapped some core functions from R Mathlib in a class TMLMath: These are: dnorm, pnorm, qnorm, pt, qt, pbeta (see R-help: http://stat.ethz.ch/R-alpha/R-patched/doc/html/packages.html) Based on these functions I have implemented the R function t.test for student t-test, and p.adjust (adjust p-values for multiple comparisons) as a class TStudentTest, which is derived from a base class TUnivariateTest. (I intend to implement further derived classes such as TWilcoxTest, TKruskalTest, but this will take some time.) My intention is to supply a statistics package, which can deal with missing values. I have sent Rene a first verion, which I have developed on MacOS X, but I hope, that it will work on other architectures, too.
