Linear regression includes any approach to modelling a predictive relationship for one set of variables based on another set of variables, in such a way that unknown parameters appear linearly.

Linear regression may also refer to:

• The ordinary least squares method, one of the most popular methods for estimating a linear regression model for a univariate predictand
• Weighted least squares, used for fitting linear regression with heteroscedastic errors
• Generalized least squares, used for fitting linear regression with correlated and/or heteroscedastic errors
• Simple linear regression, the simplest type of regression, involving only one explanatory variable
• General linear model for multivariate predictands
• Generalised linear model for non-normal distributions
• Bayesian linear regression, where statistical analysis is from a Bayesian viewpoint
• Bayesian multivariate linear regression, for Bayesian analysis of multiple predictands

• Line regression
