It can be utilized to assess the strength of the relationship between variables and for modelling the future relationship between them. Non linear analysis. The case of one explanatory variable is called simple linear regression. A dependent variable is modelled as a function of correltion independent variables with corresponding coefficients, along with the constant term.

Multiple regression requires two or more predictor variables, and this is why it is called multiple regression. The process of performing a regression allows you to confidently determine which factors matter most, which factors can be ignored, and how these factors influence each other.
