The algorithm should be able to be adapted to introduce weights. It would work very similarly, only when advancing the state, it would be based on the weight rather than always effectively using (D+1). Similarly, the denominator would no longer always exactly match the number of elements, but instead it would always match the sum of the weights that were encountered. I haven't implemented this weighted variation, but it shouldn't be too much of a change. I think Boost Accumulator already does these.
