Hmm. Thanks - however I fail to figure out how to do something like:
"generate a random number with normal distribution with average avg and standard deviation stdev".
Unfortunately the package is restricted to discrete distributions so far.
Shameless self-advertisement: The random-fu package (whimsically named, sorry) implements a modest variety of continuous distributions with what I believe to be a user-friendly and flexible interface. This thread inspired me to finish up and upload the 0.1 release (just announced on haskell-cafe as well). The public interface is slightly different from earlier releases and the haddock docs for the new one failed to build on hackage, but earlier versions have essentially the same end-user interface aside from some changes in the module export lists so if you'd like to get an idea of the basic spirit of the system you can browse the docs for the earlier releases. Alternatively, feel free to browse the source and steal some of the implementations (many of which were, in turn, translated from other sources such as wikipedia or the Numerical Recipes book). Unfortunately, the old documentation is much sparser and terser than the new documentation that failed to build, but if nothing else you can download and build the docs yourself for the new one.
