 · The purpose Aggregation serves are as follows: → Data Reduction: Reduce the number of objects or attributes. This results into smaller data sets and hence require less memory and processing time, and hence, aggregation may permit the use of more expensive data mining algorithms. → Change of Scale: Aggregation can act as a change of scope or scale by providing a highlevel view of the data ...

 · Experimental evidence, admittedly on a single problem, has been presented that demonstrates that aggregationbased data mining with logistic regression is statistically as robust as detailbased data mining with logistic regression. The experiment tested the performance of 2, 3, and 4day aggregationbased models against the performance of one based on the complete detail data. .
