aggregate data in data mining

Data mining – Aggregation

Typically, many properties are the result of an aggregation. The level of individual purchases is too fine-grained for prediction, so the properties of many purchases must be aggregated to a meaningful focus level. Normally, aggregation is done to all focus levels. In the example of forecasting sales for individual stores, this means aggregation to store and day.
