Hi,

I must admit I have never used this option myself and I am not 100% sure but anyway... Quote from the documentation: "If the source example set contains example weights, these weights may be aggregated in each group to maintain the weightings among groups."

As far as I understand this (and the source code at a short glance), this basically means that example weights (encoded by an attribute with the role "weight") will be aggregated in each group with the specified function and the resulting weight is used for the new examples.

Cheers,
Ingo
