I cоllect а set оf dаtа (n = 100 оbservations) containing a single predictor and a quantitative response. I then fit a linear regression model to the data, as well as a separate cubic regression, i.e. Y = β0 + β1 X + β2 X^2 + β3 X^3 + ε. Suppose that the true relationship between X and Y is not linear, but we don’t know how far it is from linear. Now consider the testing residual sum of squares (RSS) for these two models. Which of the following statements is most accurate?
