    Using Radio's Multi-Week Cume Rule
    How do you calculate a 2, 3 or 4-week cume from single-week cume data? We have instructions on how to do this, adapted from the Radio Multi-Week Cume Rule, which is based on copyright data that Arbitron developed from multi-week diary testing in 1985. The rule is the basis for many of the multi-week reach and frequency calculations that many processing systems use today.

    Multi-week estimates calculated with this formula are not actual Arbitron estimates, but are estimates based on a model.
