(Redirected from Regression)
Regression quantifies the relationship between an outcome variable and one or more predictor variables. It is primarily used to understand causal relationships. For example, how will sales increase if price is dropped by $1? How is life expectancy changed by consumption of a new drug?
The above definition is very broad and encapsulates much of machine learning. However, most of the time when people refer to regression they are referring to Linear Regression.
