10. (6 pts) Suppose you have a time series of closing stock market prices for company A over each trading day in a year. You decide to use Loess as a smoother but you are not sure what span to use and what degree polynomial you would use for the local smoothing. You are requested to use a polynomial of degree 1, 2, 3, or 4 together with a span where the combination of choices minimizes SSE. Briefly describe the next steps you would take to select an optimal span and an optimal degree polynomial in the loess smoothing.~ 11. (6 pts) Suppose a researcher has n observations from an experiment on a quantitative response Y and variables X1, . . ., Xk. The researcher's plan is to perform both a Ridge Regression and LASSO. Due to a programming error, the researcher duplicates the X1 column of the X-matrix prior to execution of the analyses, so that there are two identical columns of the X matrix.
