Linear regression (disambiguation)

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
