David:
I think you missed my point. As I understand him, Dmitri mentioned
rounding off to e.g. 2 decimal digits and multiplying by 100 to
produce integer weights, which would then lead to "unrolling" the
vector via rep(). Your "weighted moments" reference is probably
closer to what he sought, however.
Cheers,
Bert
