- Consider a dataset containing the following 5 data points. i 1 213 4] 5 Xi || 21]35|42]48|52 Y, |28 45| 7 | 83|63 You are asked to estimate the probability density function of X from the data with different methods. Note that you need to show intermediate steps to get the full credit. (a) (10 points) Estimate the density at z, = 4 with quartic kernel function with h=1. Note that the quartic kernel is 15 2\\ 2 K(u)=16(1u) 1(lul
