Compute the efficiency of each of the kernel functions given below relative to the Epanechnikov kernel.

a. The Biweight kernel function, given by \(\frac{15}{16}\left(1-t^{2}ight)^{2} \delta\{t ;[-1,1]\}\).

b. The Triweight kernel function given by \(\frac{35}{32}\left(1-t^{2}ight)^{3} \delta\{t ;[-1,1]\}\).

c. The Normal kernel function given by \(\phi(t)\).

d. The Uniform kernel function given by \(\frac{1}{2} \delta\{t ;[-1,1]\}\).
