WebbIn 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 called multiple linear regression. WebbIn simple linear regression, both the response and the predictor are continuous. In ANOVA, the response is continuous, but the predictor, or factor, is nominal. The results are …
