Classification versus regression


Methods for prediction can be divided into two general groups, based on the outcome of the prediction algorithm, as follows:

  • When the data is discrete, we will refer to it as classification. Discriminant analysis and pattern recognition are the other similar terms used for classification.

  • When the data is continuous, we will refer to it as regression. Other terms used for regression are smoothing and curve estimation.
