Technical details

  • Variables from Pick Any and Pick Any - Grid questions can be included.
  • The analysis generates a list of the most optimal portfolios in terms of reach and then frequency, for each portfolio size in a specified range of portfolio sizes. The results of the TURF analysis are displayed in a new text item in the report tree.
  • The filters and weight are selected via this QScript and not via the usual drop-downs at the bottom of the window. The analysis is run only on the respondents without missing data for all alternatives.
  • Options such as forced alternatives and mutually exclusive alternatives may also be specified. See Total Unduplicated Reach and Frequency (TURF) for more information on the options available in this QScript.
  • There is an option to output tables in a format that can easily be copied and pasted into Excel (tab separated columns). This format is less readable when portfolio names are long, as names wrap around to the next line. It is therefore recommended that the standard format (not Excel friendly) is chosen when Excel exporting is not required.
  • Requires Q 4.8.6 or later.
