Linear regression plays an important role in the subfield of artificial intelligence known as machine learning. The linear regression algorithm is one of the fundamental supervised machine-learning algorithms due to its relative simplicity and well-known properties. History 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 relaxed. Simple and multiple linear regression The very simplest case of a single scalar predictor variable x … Se mer Linear regression is widely used in biological, behavioral and social sciences to describe possible relationships between variables. It ranks as … Se mer In a multiple linear regression model $${\displaystyle y=\beta _{0}+\beta _{1}x_{1}+\cdots +\beta _{p}x_{p}+\varepsilon ,}$$ parameter $${\displaystyle \beta _{j}}$$ of predictor variable $${\displaystyle x_{j}}$$ represents the … Se mer A large number of procedures have been developed for parameter estimation and inference in linear regression. These methods differ in computational simplicity of algorithms, … Se mer Least squares linear regression, as a means of finding a good rough linear fit to a set of points was performed by Legendre (1805) and Gauss (1809) for the prediction of planetary movement.
