Another term, multivariate linear regression, refers to cases where y is a vector, i.e., the same as general linear regression. General linear models. The general linear model considers the situation when the response variable is not a scalar (for each observation) but a vector, y i. 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 … 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.
