A '''linear regression''' is a [[regression]] that is linear with respect to the unknown [[parameter]]s used in the fit. A linear regression can illustrate many relationships between variables (eg., quadratic) however, in the case of exponentional or log-linear relationships a linear regression is not an appropriate statistical test.
