DATA MINING TASKS
Classification, e.g. low, med, or hi risk credit card applicant
Estimation, e.g. probability of paying off a home equity loan => convert to 0/1
Prediction, e.g. predicting churn, who will respond,

(data mining tasks – cont.
Affinity grouping or association rules, e.g.cross-selling opportunities, product placement, etc.
Clustering, e.g. grouping like customers with no pre-set categories
Description & Visualization, e.g.intuitive graphical display of data for meaningful interpretation.

WHO ARE YOUR BEST CUSTOMERS????
The Concept is very simple (RFM):Your best customers are those who:
Have brought from you most recentlyBuy from you most frequentlySpend a lot on your products/services

Recency
Most recent date customer has made a purchase from you.
Most studies indicate that those consumers that have purchased from you most recently are more likely to respond positively to a new offer/promotion.

Frequency
How many times they have purchased from you since their initial purchase or some set date.
Customers who buy from you many times are more likely to respond positively to a new offer/promotion.
Warning: those that have just recently purchase may not have a lot of frequency but represent long term potential.

Creating RFM Codes
Excellent scoring/segmentation systemConvert raw values to categorical codes,
e.g. divide recency days into five equal groups (code 1-5).
Simplifies profiling process and processing speed.
Some loss of information.

Using RFM Cells to Predict Response
Historical Data OverlayTest Group, e.g. 40000 out of 1 million
customers, sent promotion/communication.
Gauge response by RFM GroupDemographic profiles of high response
group for projections.
