The quadratic model appears to fit the data better; it is better at capturing the proportionally higher prices for large houses. 212 SSE of linear model, (b): ˆ 2.23 10 SSE e i SSE of quadratic model, (c): ˆ2122.03 10 SSE e i The SSE of the quadratic model is smaller, indicating that it is a better fit.

Package ‘effects’ - R

modelis an appropriate fitted-model object. Additional arguments to allEffects, predictorEffects and plot can be used to customize the resulting displays. The function effect can be employed to produce an effect display for a particular term in the model, or to which terms in the model are marginal.

10. What is the marginal change in textbook price for each additional page? Marginal change is simply the slope of the regression line. Hence, the marginal change for our example is -0.111 dollars/page. In other words, the price of an introductory statistics textbook decreases by an average of $0.111 for each additional page.
