DPMC Method
DPMC methods are based on the crossing of "scanning" methods allowing to eliminate inactive variables and/or covariates and/or unstable, and iterative methods.... Generaly, the bases we analyze are "customers" and "prospects" bases, or "sales slip". We can also create "Mega Bases" by merging several bases (for example, in retail: bases internal turnover by POS and external databases: competition pressure, household consumption, etc. )
