For my first contribution to the Haskell community, I was thinking of releasing a statistical computing module.  Using google code, I found a few Stats.hs files contained in various projects, therefore I think it would be a good idea to have a unified module.  Currently, my module contains all the base functions one would expect: arithmetic/geometric/harmonic mean, median, mode, range, average/standard deviation, variance, interquartile range, kurtosis and skew.  Plans moving forward include histograms, covariance and principal and independent components.  What would you all like to see in a module like this?

Thanks very much,
Marshall
