NaN in weighted statistics and Score

Reported by: Peter Owned by: Peter

Component: statistics Version: trunk

In all the weighted functionality a value x is accompanied by a weight w. In the special case, yet very common, when the weight is ZERO and the value in NaN, we must take care of that. The most frequent operation is multiplying w*x, which of course results in NaN. What we need is something that return zero here.
