RFMP: Recency, frequency, monetary value, product; a more complex version of RFM that includes the product variable as a scoring factor. If you sell several categories of product or mail several titles, adding the product variable to your RFM scores can prevent you from, say, mailing an offer of PC software to Macintosh users.

Regression analysis: Modeling method that takes into account historical and demographic variables and relies on statistical calculations to weigh the variables.
