Produce a plot of a kernel density estimate of the pdf of male. earnings. Overlay a plot of the skewed t-density with MLEs of the parameters. Make sure that the two curves are clearly labeled, say with a legend, so that it is obvious which curve is which. Include your plot with your work. Compare the parametric and nonparametric estimates of the pdf. Do they seem similar? Based on the plots, do you believe that the skewed t-model provides an adequate fit to male.earnings?
