M4 Documentation:

In this chain the data from the billing department is prepared for mining. The billing department has delivered a table (represented by concept InputRevenues) that contains an entry with the revenue the company was able to generate from each client, for each month of a 2-year period. The representation of this data is changed so that six attributes are available for each client that represent the six revenues of the six months before churning, or the last six months for customers who have not churned.
