What does R-sw Discriminant do?
- it provides a lists of all possible combinations of TURF items (or the top 10, 100, etc.) sorted by their reach value in descending order.
- input data could (a) represent exposure / non-exposure of respondents to individual TURF items or (b) represent information on the level of exposure, possibly reflecting the exposure (or purchase) frequency;
- if required, weights can be specified for respondents and/or TURF items;
- the size of the combinations required can be specified (e.g., combinations of 4 items);
- if required, some TURF items could be forced to appear in each combination;
- if cost of individual TURF items is specified, each combination provided includes the total cost of the items in the combination; this is used to filter out combinations based on the total cost so that, for instance, only combinations with a total cost lower than a certain threshold are kept (to show combinations within budget);
- various depth of analysis can be specified (default: depth 1);
- data can be easily imported and outcomes can be exported as CSV/text files.
