does anyone use statistical functions like weighted mean, weighted deviation, distribution function of a standard normal distribution..? Especially the latter one is highly sophisticated since it needs some numerical approximization called trapecoid integration et al. I need the implementation of this function in pure Java 1.1. I appreciate any help (link to a free library, source code, ..). I hope I caught anyone's interest.
Many thanx in advance
