Linear progressions
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 explanatory variable is called simple linear regression; for more than one, the process is … 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 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.
