Regression Analysis with R

Understanding regression concepts

Regression is an inductive learning task that has been widely studied and is widely used in practical applications. Unlike classification processes, where you are trying to predict discrete class labels, regression models predict numeric values.

From a set of data, we can find a model that describes it by the use of the regression algorithms. For example, we can identify a correspondence between input variables and output variables of a given system. One way to do this is to postulate the existence of some kind of mechanism for the parametric generation of data; this, however, does not contain the exact values of the parameters. This process typically makes reference to statistical techniques.
