Originally posted by: rboccuzziThere is a new Dimensional Aggregator node in LAE 4.5.0. This node performs many of the actions of the deprecated Dimensional Analysis node, but is more flexible:
- The new Dimensional Aggregator node replaces the two-source Dimensional Analysis node with a single-source interface and allows users to define any tally set comparison functions using the full set of LAE nodes and BRAINscript.
- Thus, the user is not limited to two-source tally comparisons, and�when performing two-source comparisons�is not limited to the ratio calculations provided by the Dimensional Analysis node.
If you have a graph containing a Dimensional Analysis node and you want to convert the graph to use the new Dimensional Aggregator node instead, follow these instructions:
- Replace the existing node with a two-input Composite node containing:
- Two Dimensional Aggregator nodes,
- One Join node to compile the two sets of tallies,
- One Filter node that implements the comparisons.
- Pass the parameters on the composite node to the internal Dimensional Aggregator nodes (which have different names from the Dimensional Analysis node).
- Set the Join node to use the DIM1_NAME, DIM1_VALUE, DIM2_NAME, and DIM2_VALUE fields from each Dimensional Aggregator node as a match key, and to output each of the <FIELD>_TOTAL fields and the OCCURRENCE_COUNT field from each node with a new prefix of TEST_ or CTRL_, depending on the source aggregation.
- Set the Filter node to use these TEST_<FIELD>_TOTAL and CTRL_<FIELD>_TOTAL as arguments to new RATIO calculations, using the formula (CTRL_<FIELD>_TOTAL - TEST_<FIELD>_TOTAL) / (CTRL_<FIELD>_TOTAL + TEST_<FIELD>_TOTAL).
- The resulting output from this new Composite node now contains each of the tally key fields and calculations produced by the original, deprecated Dimensional Analysis node.
