Webb20 feb. 2024 · Multiple linear regression is somewhat more complicated than simple linear regression, because there are more parameters than will fit on a two-dimensional plot. However, there are ways to display your results that include the effects of multiple independent variables on the dependent variable, even though only one independent … Numerous extensions of linear regression have been developed, which allow some or all of the assumptions underlying the basic model to be relaxed. The very simplest case of a single scalar predictor variable x and a single scalar response variable y is known as simple linear regression. The extension to multiple and/or vector-valued predictor variables (denoted with a capital X) is k…
