RDF 1401: Overlapping Promotions - Enhanced Approach

Hello All,

Following up with my earlier post on promo lift calculation for overlapping promotion. Could anyone please explain the calculations behind overalapping promotions when we use the Enhanced Approach.

1. The results of comparing adjustable and enhanced approach are drastically different under same environment conditions (e.g same set of promo variables with no change in historical data set and no change to future promo variable indicators).

The retailer has a good history of promotions, hence if we could get some calculations behind enhanced approach and how lift factor is arrived at, then we can recommend whether adjustable works better or enhanced approach works better,
