Marketers use this kind of data validation:
A. time series sales model
Explanation:
The time series sales model usually works for marketing campaigns because ultimately the marketeer wants to understand how many sales are being converted from primary and secondary sources.
This then leads to the cost and result assessment of the firm.
So, the time series sales model tells when how many sales are being done with some semblance of a filter for the secondary sources from the data of the marketer that they would have.
