Question: (d) When representing a non-normally distributed random vector with either the KLE or the gPC expansion, what is the advantage of using the gPC expansion?

(d) When representing a non-normally distributed random vector with either the KLE or the gPC expansion, what is the advantage of using the gPC expansion? O The gPC expansion results in a smaller number of expansion terms O The gPC-germ is guaranteed to be independent, the random variables in the KLE are not O The germs in the gPC expansion will have a smaller variance
