Least-angle regression is an estimation procedure for linear regression models that was developed to handle high-dimensional covariate vectors, potentially with more covariates than observations. The Theil–Sen estimator is a simple robust estimation technique that chooses the slope of the fit line to be the median of … Se mer In statistics, linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables). The case of one … Se mer Given a data set $${\displaystyle \{y_{i},\,x_{i1},\ldots ,x_{ip}\}_{i=1}^{n}}$$ of n statistical units, a linear regression model assumes that the relationship between the dependent variable y and the vector of regressors x is linear. This relationship is modeled through a … Se mer Numerous extensions of linear regression have been developed, which allow some or all of the assumptions underlying the basic model to be … Se mer Linear regression is widely used in biological, behavioral and social sciences to describe possible relationships between variables. It ranks as one of the most important tools used … Se mer In a multiple linear regression model $${\displaystyle y=\beta _{0}+\beta _{1}x_{1}+\cdots +\beta _{p}x_{p}+\varepsilon ,}$$ parameter Se mer A large number of procedures have been developed for parameter estimation and inference in linear regression.
