In today''s world raw data is being collected by companies at an exploding rate. For example, Walmart processes over 20 million pointofsale transactions every day. This information is stored in a centralized database, but would be useless without some type of data mining software to analyze it.
Data mining can help build a regression model in the exploratory stage, particularly when there isn''t much theory to guide you. However, if you use data mining as the primary way to specify your model, you are likely to experience some problems. You should perform a confirmation study using a new dataset to verify data mining results.
