Take the cps09mar dataset (full sample).
(a) Estimate a 6th order polynomial regression of log(wage) on experience. To reduce the ill-conditioned problem first rescale experience to lie in the interval [0,1] before estimating the regression.
(b) Plot the estimated regression function along with 95% pointwise confidence intervals.
(c) Interpret the findings. How do you interpret the estimated function for experience levels above 65?
