The AB Controls tool matches one to ten control units (e.g., stores, customers, etc.) to each member of a set of previously selected test units, based on criteria such as seasonal patterns and growth trends for a key performance indicator (e.g., sales, traffic), along with other user provided criteria (e.g., trade area or demographic characteristics). Possible control units are matched to a user provided set of treatment units using nearest neighbor methods based on a kd-tree algorithm.*
This tool uses the R programming language. Go to Options > Download Predictive Tools to install R and the packages used by the R Tool.
The identifier field for the treatment units: The field with the treatment unit identifier for the Treatments input. This field must be some sort of character based type such as String or V-String.
The unit identifier field for the selection measures: The field with the unit identifier for the Data input of measures on which to base the match of controls to treatments.
Select the numeric measure to match control units to treatment units: The fields in the Data input upon which to base the match of treatments to controls.
Number of control units per treatment unit: The number of control units to match to each treatment unit, which can range from 1 to 20.
Allow each control unit to be assigned to only a single treatment unit: A checkbox option to make each control assigned to only a single treatment unit, by default this is true.
Graph resolution: Select the resolution of the graph in dots per inch: 1x (96 dpi); 2x (192 dpi); or 3x (288 dpi). Lower resolution creates a smaller file and is best for viewing on a monitor. Higher resolution creates a larger file with better print quality.
Controls (C): An Alteryx data stream with the field Controls, the unit identifier code for each control unit.
Assignment (A): An Alteryx data stream with the field Treatment that gives the unit identifier code for each treatment unit, and the fields Control 1 to Control N (where N is the user provided number of controls per treatment unit that given the unit identifier code for each control unit assigned to a particular treatment unit, and is provided for diagnostic purposes.
