Assignment Task: Two questions for you. Consider two regression models. One is a natural cubic spline with 15 degrees of freedom. Another one is a degree-14 polynomial (with 15 degrees of freedom). What would we expect to see in terms of the fit around the boundary (where predictor values are very small or very large.) & Is there a relationship between the number of cuts of step functions and the model’s flexibility? If so, please explain.
