That being said, most of you love Cyber Monday.
So here's what I'd like for you to do. Create a regression model with the following variables.
- RFM-based variables for 2009.
- Dummy indicators, one for each day of the year in 2009.
- Total profit dollars generated, per customer, in 2010.
If the variable comes up in the bottom 1/4th of all days in 2009, then consider what your promotional strategy should be during Cyber Monday 2010.
