NettetLinear Hypothesis: Regression (Basics) S. Weisberg, in International Encyclopedia of the Social & Behavioral Sciences, 2001 3 Multiple Regression. Many regression problems require consideration of more than one predictor, and it is required to understand how the response y depends simultaneously on the predictors x 1, x 2,…,x p.For example, the … NettetBelow is a plot of the data with a simple linear regression line superimposed. The estimated regression equation is that average FEV = 0.01165 + 0.26721 × age. For instance, for an 8 year old we can use the equation to estimate that the average FEV = 0.01165 + 0.26721 × (8) = 2.15. The interpretation of the slope is that the average FEV ...
