Join Ron Davis for an in-depth discussion in this video Models, induction, and prediction, part of Learning Excel Data-Mining.
- Types of Mining Models…In general, the data mining model,…just like a business model is a simplified representation…of reality that we create to serve some purpose.…We say it is simplified because it is based…on some assumptions, which we hope to be valid,…about what is and is not important for the specific purpose.…The Predictive Model…In data mining, a predictive model…is a formula for estimating the…unknown value of interest, known as the target.…
