Data Cubes and cuboids - Google Groups

Aggregate cells are cells from a nonbase cuboid. Those cells aggregate over one or more dimensions, where those dimensions will be called as “*” in the cell notation. So a cell notation could be (*, d2, d3, … , d9, d10) for example. It is defined that each cell generates 2n – 1 nonempty aggregate cell. As we have got three cells, we ...

Aggregations | KNIME

This workflow shows the many aggregation options that the GroupBy node offers. We start from customer data, group on Gender or more features, and run a few different aggregation methods on a few different features. Here we demonstrate grouping on multiple features, pattern based grouping and aggregation without grouping for calculating statistics.
