NettetThe linear regression model has a form like this: Y' = a+b1X1+ b2X2. With models of this sort, the predicted value (Y') is a line, a plane or a hyperplane, depending on how many independent variables we have. It's a line with 1 IV, a plane with 2 IVs, and a hyperplane with 3 or more IVs. Nettet1. jun. 2011 · Simple linear regression with measures of variation ( Total sum of squares = Regression sum of squares + Error sum of squares ), Standard error of estimate SEE (Residual standard error), and coefficients of determination R2 and correlation R.
